786780 - In B2G browser, window.scroll causes the scrolled area to go blank and doesn't actually scroll anything

Status: RESOLVED DUPLICATE of bug 780395

(Firefox OS Graveyard :: General, defect)

Description

[Justin Lebar (not reading bugmail)]

(I'm testing on my mac, gecko rev 859cfc40259333c (that's a git hash), gaia rev ddbd5b214ac1f3b0c.)

STR: Navigate to attached testcase in B2G browser.  Click the button at the top.  You should be taken to the bottom of the page.  Instead, the page goes blank.  If you try to scroll the page by using the mouse, you can get the content to show up again, but you haven't scrolled anywhere!

This blocks a blocker, but nom'ing this for blocking-basecamp because it's a web-facing regression.

Actually, cjones lead me to a simpler testcase, which I'll attach in a moment.

Attachment: Simpler testcase

This testcase simply calls window.scroll(0, 300) when you press the button.

Clicking the button causes a large portion of the screen (probably 300px high) to turn white.

drs tells me that this is the same as bug 780395.

Dupe is a basecamp- so -ing.  But thankfully it looks like that's getting fixed :)
