Why aren't network requests for iFrames showing in the Chrome developer tools under Selenium?

I have a use case where I need to retrieve the initiator from the Chrome Network tab. This works fine, except for the following case:




  • The iframe is HTTPS;

  • The enclosing page is HTTP;

  • The page was opened by Selenium


In this case, the network tab (and any extension on the debug protocol) show the fetch to the iframe content remains pending forever, and none of the child loads are emitted.



Changing the page URL to HTTPS, then the iframe is loaded and the child loads are displayed.



If I manually control the Selenium-opened browser and open a new tab, then it does not matter if the fetch is over HTTP or HTTPS. It really is only the tab that webdriver creates when it's loaded that seems to suffer this effect.



Is there some security protection at play, or is this just a weird bug?

                    2 I'm trying to set the .DisplayMember property of a ComboBox in C#, but I want to bind it to multiple columns in the .DataSouce . My SQL looks like this: SELECT PersNbr, PersFirstName, PersMiddleName, PersLastName FROM Pers WHERE PersNbr = :persNbr; I'm saving this query in a DataTable so each column selected has it's own column in the Datatable . I want to make the .DisplayMember a combination of PersFirstName + PersMiddleName + PersLastName so their full name appears like this: comboBox.DisplayMemeber = "PersFirstName" + "PersMiddleName" + "PersLastName" I know I can just to this on the query: SELECT PersNbr, (PersFirstName || PersMiddleName || PersLastName) PersName and then just do this: comboBox.DisplayMember = "PersName"; but I

                    Is it possible to collect Nectar points via Trainline?

                    2 Since I am not eligible for any Railcard, the only available discount/bonus scheme is Nectar Card for me. GWR, SWR, LNER and Virgin Trains allow to collect Nectar points and I have already linked a card to my GWR account. A friend suggested me to use Trainline App, because it can search for bus tickets either. I had a look at the application, but could not see any option for Nectar.
