Details

  1. Enable fission (fission.autostart preference)
  2. Open data:text/html,<html><body>Outer Text<iframe src='http://www.example.com'></iframe></body></html>
  3. Zoom the page.
  4. Reload the page.

Expected: The page is reloaded at the adjusted zoom level.
Actual: The outer page is correct, but the content of the iframe is reset to zoom level 1.

This occurs in both full and text zoom modes.

I suspect that this is because nsDocumentViewer::CallChildren iterates over docshells so doesn't assign the right zoom level to each subframe.

How does it work when we set the zoom initially? Do you know why we're taking a different path for setting the zoom, vs restoring it on a reload?

M6 because zooming doesn't block dogfooding.

Fission Milestone: M5 → M6

Looks like it works fine now. Neil, can you please double-check?

Yes, this appears to be fixed. I'm going to close it. Not sure if it was fixed by Emilio's work in bug 1612068?

Yes, sounds p. likely.
