Closed Bug 567186 Opened 10 years ago Closed 10 years ago
When possible, set viewport size before page finishes loading
Most pages in Fennec start loading at one size, and then are resized based on the viewport settings after they finish loading. This is visible to the user. This patch uses a new event DOMMetaAdded event to update the viewport settings as early as possible. This eliminates most of the cases where the page resizes after loading. (It still happens on sites with mobile doctypes rather than meta tags, like http://m.facebook.com/ .) This depends on the platform patch in bug 567183. All viewport test cases still pass with these patches applied.

In updateViewportSize you'll hit the empty object for metaData, right?

This resets the default viewport settings, so if the new page does not set use <meta name="viewport"> it will start rendering at the default settings, instead of the previous page's settings.
