        <pre>Description:
Using Tabbed User Interface some larger (over 1MB) XLSX sheets do not load
instead LibreOffice freezes.  The files do open when using the Standard Toolbar
UI.

Also, switching to a tabbed interface (from Standard Toolbar UI) when having
the same XLSX file open freezes LibreOffice.

FILEOPEN, UI

Steps to Reproduce:
1. Switch To "Tabbed" User Interface
2. Double Click on large XLSX file
3. LibreOffice takes a while to load the file and eventually freezes


Actual Results:
Total LibreOffice Freeze

Expected Results:
File opens in due time


Reproducible: Always


User Profile Reset: Yes
