Description Mihai Balan 2013-04-17 01:05:52 PDT
Created attachment 198476 [details] Test-case Positioned content generated by MathJax gets clipped or rendered invisibly, depending on the position of the region against the viewport. Reproduction ------------ - open attachment - click on the button Actual ------ For each click, the region moves down and some of the equation gets clipped (not all of it) Expected -------- For each click, the region moves down but the equation keeps showing

This bug doesn't repro for me in today's nightly (r151260).

But does the formula renderer? I need to download the attachment and open it locally for the test to work. I can still reproduce this in Chrome Version 29.0.1530.2 dev.

(In reply to comment #2) > But does the formula renderer? I need to download the attachment and open it locally for the test to work. I can still reproduce this in Chrome Version 29.0.1530.2 dev. It seems the bug repros in Chrome like you say, but not in Safari. I only tested Safari. Thanks for the info!

(In reply to comment #4) > Works for me on today's nightly (r151543) Look at the above comments- We should post a Chromium bug for this issue since it doesn't repro in Safari.

I've logged https://code.google.com/p/chromium/issues/detail?id=249715 for Blink.
Comment 7 Mihai Balan 2013-06-14 05:22:14 PDT
Keeping this open so that we don't forget to import the test when this gets fixed in Blink.
