Bug: When enabling: "Calculate folder sizes" sometimes the Column Headers become frozen

### Description

Randomly, if I have the setting Calculate folder sizes enabled, the Column Headers become "frozen" and I can't resize them.

### Steps To Reproduce

Enable the Setting: "Calculate folder sizes"

Randomly upon opening Files the Column Headers will be in frozen state where you can no longer resize them

I also have the setting: "Leave app running in the background when the window is closed" enabled. I'm not sure if this has anything to do with it, but I just wanted to make sure I included it just in case.
