Description

[Kartikaya Gupta (email:[e-mail])]

From https://bugzilla.mozilla.org/show_bug.cgi?id=810171#c15:

Case 1: On the Galaxy Nexus in portrait orientation
Load news.ycombinator.com
Tap on Search field at bottom of page
a) -> sometimes VKB comes up, page is zoomed and repositioned, but Search box is not visible (it is off to the right)
b) -> sometimes VKB comes up, page is repositioned but not zoomed, Search box is obscured by VKB

Case 2: Galaxy Nexus in portrait orientation
Load robocop_input.html (from testVkbOverlap)
Scroll down and tap input field
a) -> usually VKB comes up, page is repositioned and zoomed, input field is visible (works correctly)
b) -> sometimes VKB comes up, page is repositioned (and zoomed?), but input field is partially obscured by VKB

Case 3: Galaxy Nexus in landscape orientation
Load robocop_input.html (from testVkbOverlap)
Scroll down and tap input field
a) -> VKB comes up and obscures input field (consistently)

Comparing cases 2a) and 3a), I noticed that, in landscape only, _isRectZoomedIn returns true here:

Attachment: partial solution

This addresses Case 3 only...more to do here.

Changes in bug 830760 may affect the behavior here.

Comment 4

[Geoff Brown [:gbrown]]

I tested with the 2 patches in bug 830760 + the patch from Comment 2: Case 1 is also improved -- usually the Search field is visible. I still see intermittent problems for all cases; not sure what is different from one tap to the next.

Comment 5

Re-tested with the final patches landed in bug 830760: all of the anomalies identified here are fixed.
