989032 - When switching monitors, the toolbox can completely hide content, difficult to fix

Status: RESOLVED DUPLICATE of bug 988982

(DevTools :: Framework, defect)

Description

[Jeff Griffiths (:canuckistani) (:⚡︎)]

STR:

* somehow acquire an 11" air and attach a 1080p monitor to it
* open nightly on the 1080p screen
* in about:config, set devtools.toolbox.footer.height to 700
* open the devtools in a tab ( toolbox should be docked to the bottom ), toolbox height should be 700
* drag the window over the the macbook Air's 1366x768 screen

Result: the toolbox now covers all content in the tab, and there is no way I can see to drag it down and reveal content. Note that this will also happen and is particularly annoying when detaching the external monitor.

Workarounds: 
* drag the window back to the 1080p monitor and maximize it
* go into about:config and set devtools.toolbox.footer.height to something like 400, then close and re-open the toolbox.

Aside: not sure what I'd want to happen, I expected to be able to drag the toolbox down when it covered all content. I also wondered if we could catch the event for when the window is dragged from one monitor to another ( assuming there is one ) and then ensuring that a minimum amount of content remains visible.
