Steps to reproduce:

1. Copy this to your clipboard: "<iframe src="" flex="1" target="_top" name="test" id="test" />"
2. Open Browser Toolbox
3. Right click on the first <deck> child of window

Note: After this step your Firefox UI will be filled with an iframe, you can undo this by Cmd/Ctrl+Z
4. Paste -> As first child
5. Hover over the element saying "I have a title attribute"

Actual results:

No tooltip shown

Expected results:

A tooltip with contents of title attribute should be shown

You can confirm this works outside chrome code by running the attached test.xul as remote XUL in Firefox (
