Hi, a silly but annoying bug.
Numbers in the color mixers on the text style editor cannot be entered with keyboard. It let you select values with the mouse but in does not accept any keyboard input, so you can only adjust color with the sliders. It happens both in paragraph and character style editors.
Steps: Double click on a style to open the editor, go to any color setting and try to modify a color by entering number on a field.
This issue seems to occur on 1.9.1, it was not present on 1.9.0 (at least that I noticed)
Publisher 1.9.1
MacOS 11.2.2
