Hello!
I created a very simple PCF, a SingleLine.Text with an HTML password attribute:

It looks nice, like a standard field, but the reality is that there is custom CSS, some of it I copied from other PCF's in Github and some other properties I had to tweak them myself. If I don't add CSS it looks like:

The problem with that is that when Microsoft changes the CSS, for example making the border blue on hover my PCF will retain the old design.
Microsoft uses this classes:

The problem is that those classes are dynamic, so I cannot have my input the classes "pa-x pa-bv..." because won't work in the next refresh.
Any ideas of how to use the default classes/CSS without hardcoding them in my PCF CSS file?
Thanks
