In Lightroom Classic CC 8.1, the inputs for develop settings accept alphanumeric characters instead of only numeric ones, which causes accessibility issues because it unnecessarily breaks keyboard shortcuts while the input is in focus.
I'm a heavy keyboard user in Lightroom, so a common workflow for me in the "develop" tab is to move from setting to setting using the tab key, then modify the setting using the up and down keys, or by directly typing a number, and pressing "J" to toggle shadow and highlight clipping. In Lightroom Classic 8.0 and below, this worked fine. In Lightroom Classic 8.1, pressing a keyboard shortcut like "J" while an input is selected results in this:
This of course results in a error message because "j" is obviously an invalid value, so why let me enter it to begin with? Could you go back to the previous behavior, which was ignoring non-numeric values on these inputs, so the keyboard shortcuts aren't broken?
