[Affected versions]: Firefox 57.0a1 (BuildId:20170906220306) Firefox 56.0b9 (BuildId:20170903140023) [Affected platforms]: Windows 10 64bit Mac 10.11.6 Ubuntu 16.04 64bit [Steps to reproduce]: 1. Launch Firefox. 2. Access the https://devtools-html.github.io/debugger-examples/examples/todomvc/ webpage. 3. Open the debugger. 4. Open the todo-view.js file. 5. Add a breakpoint at line 34. 6. Add an todo item in the UI. 7. Expand the "Initialize" from the Scopes panel until the items are no longer visible. [Expected result]: An horizontal scrollbar is displayed at the bottom of the panel as soon as the items are no longer visible. [Actual result]: An horizontal scrollbar is displayed at the bottom of the panel only if scrolling at the bottom of the Scopes panel. [Regression range]: I don't think that this is a regression. [Additional Information] Please observe the attached screencast for further information about this issue.
Note that having a global horizontal scrollbar comes with its own set of issues. See discussion on https://github.com/devtools-html/debugger.html/issues/3380 for instance. If the object inspector makes the whole side panel wider, and thus creates a global horizontal scrollbar, we must be careful of not hiding all the actionable elements located on the right of the panel: close icons for breakpoints and watch expressions, icon-buttons on the top of the side panel etc...
