The problem happens in Blender 3.6.0 LTS.
It happens when I zoom very close to a face with low angle,
when I click on the face, blender select the face behind it.

I tested on Blender 3.5 and it has no problem at all.
I used the same blender file in Blender 3.5, and it worked without bug.

It is easy to reproduce the bug. Create a very big plane, then add some very small cubes on top of it.
Then zoom to the cubes (very close) and pan the view to low angle.
Now try to select the cubes, blender will give wrong face selection.
(I attached a video, also uploaded on youtube).

I guess we can close this as the twitter thread conclusion seems to be that it is fixed in master?
@Lateasusual do you have the commit hash for the fix?

It was fixed by 70b05249cb

but I noticed it was already included in the list of changes to be backported in #109399
