Bug 34042 – visibility:hidden iframe captures contextual click.

• Component: Frames
• Status: RESOLVED CONFIGURATION CHANGED

[Derk-Jan Hartman]

I'm attaching a html case with an iframe within an absolute positioned div. The div has visibility:hidden

Try to right click the link on the webpage. You will be presented with the contextual menu for the frame. The contextual menu options for the link are missing. This is annoying when trying to open a link in the new tab or new window, but even more annoying in that all elements behind this invisible iframe cannot be directly inspected with right-clik "Inspect Element". A mid mouse button click does force the opening of the link in a new tab. The problem can be worked around by using "display:none;" instead.

The bug is present in Safari 4 and the latest nightly (6531.21.10, r53765).

This is still present in the latest nightly build (r241015 - 2/6/19) and in production.

The use case we have is that we are a video player that sometimes plays ads in iFrames on top (in terms of z-index) the player. In between ad breaks, we put visibility: hidden on the iFrame. In all browsers, except Safari, right-clicking on the player will bring up the proper contextual menu from the player itself. However, in Safari, the event is still passed to the iFrame and the user sees the contextual menu from the iFrame.

We built a page, linked below, that plainly shows the behavior:

In searching Bugzilla, it looks like similar issues were reported back to 2009 (#26649).
