Bug 105097 – SVG images are sized incorrectly on first load

• Component: SVG
• Status: RESOLVED FIXED

[Philip Rogers]

On first load, SVG images that depend on the image size will be sized incorrectly. Additionally, the SVG image cache is not used much of the time because it depends on a call to CachedImage::setContainerSizeForRenderer(...) that it never receives.

Patch forthcoming!

We should clear pending requests after we send them.

We should just remove "renderer" from this.  It's somewhat of a layering violation IMO for the loader to know anything about the rendering tree.  This can be in a follow-up patch if you'd rather.

I agree; lets do it as a followup though. I filed WK105244 to track this.
