Stack trace

Description of problem:

When I want to detach the developer tools from the main window by using the "Separate Window" option in the three-dot menu, Firefox on Wayland crashes.

Should I report this to Mozilla Bugzilla?

Version-Release number of selected component (if applicable): 67.0-4.fc30

How reproducible: Always

Steps to Reproduce:
1. Open developer tools (CRTL+Shift+I or from Tools->Web Developer->Toggle Tools)
2. Click the three-dot menu
3. Choose "Separate Window"

Actual results: For an instant, the window appears. Then Firefox crashes with SIGSEGV.

Expected results: The tools should be detached to a separate window and Firefox should continue working.

Additional info: Stack trace is included in the attachment.

Same goes for re-attaching the window.

1. Exit Firefox on Wayland
2. Bring the window in position using non-Wayland Firefox
3. Exit non-Wayland Firefox
4. Start Firefox on Wayland

I've tried the latest nightly, 69.0a1 (2019-06-30) (64-bit). Still getting a crash.
