[webkit-dev] Making PopupMenuClient testable

Johnny, I'm not sure what you mean. By the render dump, do you mean the
pixel dump? Popups don't show up in pixel dumps. I'm not sure what
information you can get from that.

The bug that I'm trying to address, is, among other things, the bounding box
rect of the PopupMenuClient that is passed into the platform layer to show
the popup does not take transforms into account. My solution in 69631 is to
expose the bounding box rect through the PopupMenuClient interface and make
it testable through window.internals. I've also included a layout test to
show how one would test this. Right now the test fails, but once 66062 is
applied the test will pass.

Is this a reasonable approach?
