Video demo: I had to reopen inspector for it to go back to normal

In the source editor in the inspector's Sources tab, if there's currently a file selected and being viewed and you navigate the browser to a new webpage, the source editor becomes blank, which is understandable since the file that you were viewing is now gone with the old webpage.

   - If you that new webpage is about:blank, then the source editor will show a loading icon that spins forever, instead of showing a gray "about:blank" watermark text as it normally does
   - If the old webpage was about:blank and you navigate into any other webpage, the source editor will show the red text "An error occurred trying to load the resource", and worse, that text won't disappear at all even if you select other files. You have to reopen the inspector for that source editor to behave normally again

See attached for a video demo.
