When I add an object into my presentation, enter some text into the object and then select the text to change the font size, the font-size input loses focus when I type the new font size. This happens in the Tabbed Interface. I posted an unlisted video on youtube showing the bug: https://www.youtube.com/watch?v=tFmI_attuJI Steps to reproduce: 1) Add an object into the presentation (ex: a rectangle) 2) Select the rectangle, press F2 and enter some text 3) Select the text you've just entered 4) Click the font-size input (not the dropdown list) and try to enter a number (ex: 20) 5) Notice that when you type the number, the font-size input loses focus, and the cursor returns to the object I am using LibreOffice 7.0.1 on Ubuntu 20.04 / Gnome 3.36 and Nvidia graphics.
I have just noticed that the exactly same thing happens if I try to change the font using the same method. After I select the text, if I click the font-name input and try to type in a new font name, the font-name input loses focus and the cursor returns to the object.
