612999 - Frontend auto-fits pages if they resize after loading

Status: RESOLVED WONTFIX

(Firefox for Android Graveyard :: Panning/Zooming, defect)

Description

[Chris Jones [:cjones] inactive; ni?/f?/r? if you need me]

STR
 (1) Load http://people.mozilla.com/~cjones/expando.html in portrait orientation

The initial page is 800px wide so doesn't get auto-fit.  After 2 seconds the resizes itself to 2000px wide, and thereafter flips back and forth every 2 seconds.

Every time the page resizes to 2000px wide after load, it's auto-fit.  I consider this a bug, because it's going to lead to a bad UX on pages that dynamically resize, and there's nothing web authors can do about it.  I don't think the frontend should try to auto-fit at all after page load.

Agreed, though it might be tricky to define when "page load" is finished, given the existence of pages that generate all their content through JavaScript after the pageload event fires.
