Deselecting multiple files by clicking on filename takes too much time on detailed list

As I observed here, this action takes a long time compared to deselecting by clicking on "type" column and CPU usage increase while Thunar freezes.

Steps to reproduce:

1. Select multiple files (/bin/ folder for example) on detailed list
2. Deselect by clicking on filename
3. Wait until deselection end

I'm using Xubuntu 20.04, Thunar 1.8.15 and NVIDIA Driver 440. My CPU is AMD Athlon II X3 400e (3) @ 2.200GHz and GPU is NVIDIA GeForce GT 710.
