Page reflow issue on pages with facebook and twitter button

[mpfusion]

On several pages that contain a facebook and twitter button the page continuously reflows. This only happens when the page zoom “zi” is used. Steps to reproduce:

∙ install addon vrome
∙ Settings → Web content → Font size: medium
∙ Settings → Web content → Page zoom: 110%
∙ increase page zoom one time by pressing “zi”
∙ Go e.g. on page https://latex-community.org/component/content/article/92-contests/431-gnuplot-book

This yields a page zoom of 125%. If the page zoom is directly set to 125% it works flawlessly. Set it to 110% initially and use vrome to increase the zoom one step, for the bug to show up.

I made a small screen cast of how it looks like on my system: https://freeshell.de/~mpfusion/sc.ogv

System is Debian linux, Browser chromium Version 20.0.1132.27

Yep, managed to reproduce it.
Thanks for the details. It was very helpful.

devs:
This looks like an iframe issue.
The twitter/share buttons are in an iframe and there is JS forcing the zoom reset to 100%
We set the zoom using JS in the main body and the share buttons in the iframe keep trying to reset it.

JS Zoom is different from browser zoom

Not sure how to fix. Sounds more like an edge case than a global problem.
