Main editor becomes blank when reopening an html page.

[RaymondLim]

1. Open an html page in the working set. (double-click on it in the project panel)
2. Close it by clicking on x icon before the file name in the working set. Main editor shows the content of the previous document available in the working set.
3. Reopen it from project panel tree.

Result: Main editor becomes blank.

Actually, not just html, it can be any page. and it can't be open for the second time. The title bar is still showing the previous file available in the working set.

Possibly due to my changes for #1257. Investigating.

utr if you close it with keyboard shortcut or from File > Close in step 2.

I can also reproduce it if I click on a button in the Save dialog when closing the document in step 2. So it is definitely a focus issue.
