Attachment: test.zip

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.10; rv:40.0) Gecko/20100101 Firefox/40.0
Build ID: 20150402170249

Steps to reproduce:

1. Copy this to your clipboard: "<iframe src="https://jsfiddle.net/mdibaiee/p8j4ktxL/embedded/result/" 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 (https://addons.mozilla.org/en-US/firefox/addon/remote-xul-manager/)

So apparently setting tooltip="aHTMLTooltip" on the wanted iframe works.
