Horizontal scroll of tree is partially unclickable and not highlighted from the UI

Reproduction Steps:

Create a few folders that will make a horizontal scroll inside the project
Select one of the deeply nested folders/files
Observe how it is unable to be clicked on at a certain point and the highlight is not covering the full length of the file

Expected behavior:

Should be able to click it at the line it is on and that it should be highlighted for the full length of the tree's horizontal scroll

Observed behavior:

Unable to click on file/folder if it is too far horizontally to the right. Highlight is not covering full length of tree
