Created attachment 365397 [details] Test Seen on iPad in landscape orientation. Steps to reproduce: 1. Open the attached test case. 2. Tap each popup button. After you tap each popup button, but before the popover is shown both the page and popup button shift (in opposite directions). This should not happen.

Looks like the layout changes when the popups gain content.

(In reply to Simon Fraser (smfr) from comment #3) > Looks like the layout changes when the popups gain content. This is the bug, right? No reason for the layout given the page markup (it does nothing special).

It looks like the baseline changes for the line when the input's shadow tree gains text content.
