Also, Ctrl + Shift + Reload should open new tab in foreground, but it does not. Ctrl+Shift clicking links and bookmarks opens them in new foreground tab.

Thanks for filing the issue!

Considering the case: Ctrl+Click Reload on current page & Ctrl + Shift + Reload

Able to reproduce the issue on reported chrome version 70.0.3538.67 and on the latest canary 72.0.3589.0 using Windows 10 and ubuntu 14.04
Note: Issue isn't applicable to Mac

As similar behaviour is seen from M60(60.0.3112.0) considering it as Non-Regression and marking it as Untriaged.

@1: Shift-reload has a different meaning than shift-clicking links (it does a full validation of the underlying resources).  This predates click modifiers on links and so can't really be easily changed.

We do support middle-clicking reload to duplicate to a new background tab.  I'd be OK with doing the same thing for ctrl.  Notably, ctrl-clicking the back button already does the desired thing.

I want to resolve this issue.
I think this issue seems to have arisen because of masking off Shift and Ctrl flag in ReloadButton::ButtonPressed().

Shift-clicking the back button supports to open Webcontents in new window. But, shift-clicking the reload button can't work that. Is it right?

If it is right, Can I patch for this issue?

We don't expect this to be a common case scenario, so we're going to WontFix at this time.

But the behaviour is available on Mac, will you be removing the Cmd+Reload functionality too?
