Hi all,
Specifically what Rudy encountered is a problem with iframe: there is
no specific event for a moment where
- the content is loaded (and it's window object exists and accessible
from iframe.contentWindow) so we could call
window.addEventListener('load') on the right window object.
- but before it's window.onload took place so that listener could actually fire.
Note that if you tried to get |iframe.contentWindow| as right at the
time you set iframe.src, you'll get the window object of |about:blank|
page.
We thought the special mozbrowserloadstart event from mozbrowser API
can be used, but it's not the case.
I suspect it actually depend on the size of the page loaded; just like
normal browsers, if you click on a link when using a slow network, the
spinner will start spinning ("loadstart") long before you switch to
the destination page. However, how the recent change trigger this
problem remain a mystery, as we didn't really increase the size of
system/index.html significantly.
