1933504 - Clicking on a big styletag might drag the content and move it in the markup view

STRs are not consistent, but locally it seems to help to have a toolbox height around 580px (set 580 for the pref devtools.toolbox.footer.height).

• open test case
• open devtools > inspector
• resize toolbox to be around 580px (can happen at other sizes)
• in the markup view, select a node, then select the head > style tag
• click in the middle of the style tag
  Might take a few tries, but usually at some point the content of the style tag moves outside of the style tag, into the markup view.

This looks just to be a front end issue, where we scroll the UI during the mousedown, and depending on the timing of the mouseup, it might trigger a drag and drop inadvertently.
