BuildID: 20170615070049

Steps to reproduce:
 - start Firefox DevEdition or 55 Beta 2 with a new profile
 - open a new empty tab
 - open developer tools (F12 or menu)
 - select "Network" tab

Actual results:
 the network view is "empty" (as there is no request captured yet) but a scroll bar is visible, spanning from the column headers to the footer

Expected results:
 no scroll bar should appear

This scroll bar is visible with the dark and light theme but not the firebug one.
Scroll seems to be a few pixels worth, looks like a bug.

This permanent scroll bar prevents grabbing the content's one when available.

Bug 1374042 - Fix vertical scrollbar;

Setting overflow: hidden instead of overflow-x: hidden on .request-list-container seems to fix the issue (without breaking scrolling).

It seems like a more elegant solution too.
