Clear icon inconsistent

### What Happened?

The clear (`edit-clear`) icons are inconsistent between normal and symbolic variants.

### Steps to Reproduce


### Expected Behavior

These should probably all use the same symbol. Although I'm not sure what to do as the broom looks a little like a paint brush in symbolic form, and the backspace shape is difficult to see when used as a normal icon.

I tried just the backspace style red. This makes it easy to see in dark and light themes, and gives it the "danger/destructive" color.


But, I do like the broom too. Not sure what would be best here.
