Description

[Mihai Boldan, Desktop QA [:mboldan]]

Attachment: 3pane inspector.gif

[Affected versions]:
- Firefox 62.0b4, Firefox 63.0a1 (2018-06-28)

[Affected platforms]:
- Windows 10x64, macOS 10.12.6, Ubunutu 16.04x64

[Steps to reproduce]:
1. Launch Firefox.
2. Press F12 or Right Click and select Inspect Element.
3. Make sure that 3-Pane inspector is toggled off.
4. Grab the right section separator and drag all the way to right.
5. Toggle on 3-Pane inspector.

[Expected result]:
- All the sections are visible. 

[Actual result]:
- Only the Rules section is visible. See the attached screencast.

[Regression range]:
- I will search for a regression asap.

[Additional notes]:
- Note that the panel that containing 'Layout, Computed, Animations, Fonts' can be minimized until is not visible if dragging it to the right. Maybe this is the cause of the issue.

This turns out to be a bug with our resize code inside devtools/client/shared/components/splitter/SplitBox.js.

When we hit minWidth we need to take minWidth into account.
