[Implementors/Senders] Set debug point in implementors/senders window messes with slider

[ericwinger]

Bug:
Setting a debug point in the new implementors / senders window makes the slider go crazy. Windows resize dramatically. Slider won't follow the mouse. General mayhem ensues.

Reproduction:
Open an implementors window and set a debug point. Windows resize and the slider gets goofy.

Workaround:
Set a Debug Point in a traditional browser.
Screencast:

Hopefully this screencast shows the slider not following the mouse well enough.

Thanks for the report! Sorry for this strange experience. This is why we are working on a fully new widget set.
