I'm having very weird behavior with hyperlinks in a tikzpicture. Here's a code snippet:

documentclass{article}



usepackage{tikz}

usepackage[linktocpage=true]{hyperref}

usepackage[capitalize]{cleveref}



usetikzlibrary{arrows}

tikzstyle{rect} = [rectangle, rounded corners, minimum width=8em,%

minimum height=3em, text width=8em, text centered, draw=black]

tikzstyle{rect2} = [rectangle, rounded corners, minimum width=5.5em,%

minimum height=3em, text width=5.5em, text centered, draw=black]

tikzstyle{anch} = [inner sep=0em, outer sep=0em]

tikzstyle{arrow} = [thick,->,>=stealth]



% Create a spacer to make sure box around link isn't too close to text.

newcommand{spacerrule}[3][0 em]{textcolor{white}{rule[#2]{#1}{#3}}}



begin{document}



% So the hyperlinks link to something.

label{signedranktest}

label{ranksumtest}



% Verify that the commands work outside of tikzpicture



hyperref[signedranktest]{parbox{9em}{centervspace{-1 em}spacerrule{.1 em}{1 em}%

textbf{Wilcoxon Signed Rank Test}spacerrule{-.4 em}{1 em}}}

vspace{1 em}



hyperref[ranksumtest]{parbox{9em}{centervspace{-1 em}spacerrule{.1 em}{1 em}%

textbf{Wilcoxon Rank Sum Test}spacerrule{-.4 em}{1 em}}}



begin{center}

begin{tikzpicture}[node distance=3 em]



node (samp2) [rect] {2 groups};



node (lev2b) [anch, below of=samp2]{};

node (paired1) [rect, below left of=lev2b, xshift=-3 em, yshift=-1.5 em]{Paired/matched samples};

node (indep1) [rect, below right of=lev2b, xshift=3 em, yshift=-1.5 em]{Independent samples};



node (pairtest) [below of=paired1, yshift=-2 em, text width=9em, text centered]%

{hyperref[signedranktest]{parbox{9em}{centervspace{-1 em}spacerrule{.1 em}{1 em}%

textbf{Wilcoxon Signed Rank Test}spacerrule{-.4 em}{1 em}}}};



node (indtest) [below of=indep1, yshift=-2 em, text width=9em, text centered]%

{hyperref[ranksumtest]{parbox{9em}{centervspace{-1 em}spacerrule{.1 em}{1 em}%

textbf{Wilcoxon Rank Sum Test}spacerrule{-.4 em}{1 em}}}};



draw [arrow] (samp2) -- (lev2b);

draw [arrow] (lev2b) -| (paired1);

draw [arrow] (lev2b) -| (indep1);

draw [arrow] (paired1) -- (pairtest);

draw [arrow] (indep1) -- (indtest);



end{tikzpicture}

end{center}



end{document}

When I run this, the box around "Wilcoxon Signed Rank Test" is mis-sized, with the program thinking it is only one line high instead of two. The really weird thing is that if you comment out the line starting with "node (pairtest)", then the "Wilcoxon Rank Sum Test" box is mis-sized in the same way as the other one used to be; and if you switch the order of the lines starting with "node (pairtest)" and "node (indtest)", then the WRST box is mis-sized and the WSRT box is correct! So it seems it's always the first one it encounters that is mis-sized.

Any thoughts?

Your code dates from the first versions of TikZ and is now deprecated.

The extra boxes you've added everywhere are disrupting TikZ's normal work. The easiest way here is to do everything with the new 3.0.1a's TikZ version and without having to go through additional commands that complicate his work.

So, I deleted theses boxes and updated the code.

Thus, your personal macro spacerrule is useless and to solve all your problems, just load the positioning library (read section 17.5.3 from page 229 of the manual 3.0.1a).

The tikzstyle is depreciated in favor of the tikzset.
For arrows, the library is now called arrows.meta

As promised, here's the final code that worked for me; thanks to AndréC for pointing me in the right direction. I removed my spacing macro from the WRST box to illustrate why I used it. For those of you not following our comment thread, you need to create a PDF to see the boxes around the links.
