Description Emil Tanev 2017-09-02 07:14:52 UTC
Open a word document of around 58 000 words, font size is 11
Select all
Change the font size from the drop down to the maximum - 96
Wait for the font to change
Change back to 12
Wait for the font to change
Click on the font size drop down. 

Issue: the application stalls for a long time, even though the previous font change has been applied.
