viewport key binding not work in 5.8

Summary

when I try to change the view using shortcuts it doesn’t work, I write how to reproduce it and also attach a video.

What Type of Bug are you experiencing?

Editor

Steps to Reproduce

-set in shortcut viewport for example num1 for front
-in viewport, push num1 (not work)
-click on top on one of the simbols example translate and push num1 again (now work)
-click and move in the scene
-push again num1 (not work)

Expected Result

Similar to previous versions, the view switching buttons should work at all times.

Observed Result

when I press the key (eg num1) the binding does not seem to be recognized, it is recognized if I click elsewhere for example on translate, but then as soon as I move in the scene normally (clicking in the viewport and moving the mouse) then when I press num1 again it does not work anymore.
This only happens in 5.8 and has always worked fine in other versions.
