@Campbell Barton (campbellbarton) I'm sure I mentioned this issue before but I don't see any report for it. If there is, let me know.

I am able to reproduce 2 undo steps, but path select seems to work well here.

This reminds me of the problem described in T95452: Multiple calls of 'view3d.select' with LMB selection keymap, but with selection through LMB.
In that situation, the selection operator is also called multiple times, but as the second time doesn't bring anything different, the undo step is not added.

I can imagine that editing the settings could result in problems with undo, but I also can't replicate the problem with the steps described. Is there any detail missing?

Also can't reproduce the path select issue.

Ah I see what's going on with Path Select. Since I am using a pen it is very easy to accidentally do a click-drag. Path select only happens on a click event.
So this is unrelated and not a bug. I'll remove it from the report.

@Germano Cavalcante (mano-wii) I think this is directly related to T95452. Disabling the conflicting "Edit" level selection keymap entries or the "Tweak" tool entries, solves the issues.
I think we should prioritise these bugs at some point since these conflicts have left the Tweak tool and fallback broken for both right click and left click select for at least a couple releases.
