SUMMARY
When editing the main tex file of a project, the live preview works very well. When keeping the tab of main tex file open / visible in the foreground and closing a background tab of e.g. a .bib file, the live preview disappears. To me this is (not super-annoying but) unexpected behaviour. I have to click into the main area of the editor again to a) restore the live preview and b) be able to continue writing. (Let me know if I should report the latter in a dedicated issue)


STEPS TO REPRODUCE
1. Open two tabs: the main .tex file and a .bib file
2. Make sure the tab of the .tex file is visible/active, the .bib file is in the background 
3. Click the little cross in the top-right corner of the background tab to close it

OBSERVED RESULT
The live preview of the main document, which is still visible, disappears. One cannot continue writing without clicking into the text editing area.

EXPECTED RESULT
Live preview remains visible, no need to click into the text editing area to continue writing.
