198479 - IFrame doesn't hide when setting visibility:hidden (breaks Midas demo)

Status: RESOLVED FIXED

(Core :: Web Painting, defect)

Description

IFrame, once shown, will not hide. Setting visibility:hidden only hides its
frame, but the content remains. The problem is apparent in the color pickers of
Midas demo, but I'll attach a pretty minimal test case too.

Attachment: test case

A simple test case that reportedly works in 1.3 (I haven't tested). I see the
problem at least in 2003031808, but it might be older.

This is a major problem when implementing Midas.

Attachment: fix

This broke when the logic for hiding views in response to CSS
"visibility:hidden" was loosened up. For IFRAMEs we want to hide the view in
that case, because its content will not obey our CSS "visibility:hidden".
