Flarum ColorInput textbox issues

[Ralkage]

Current Behavior

The ColorInput textboxes in Flarum, more specifically in the Admin CP under "Appearance" and new/edit groups modal, are automatically completing the hex you put in even when you don't want it to. It seems to only happen when you input consecutive lowercase letters and numbers after the pound symbol. Also, when you try to backspace to input the correct hex, it'll keep adding back whatever letter or number sequence you attempted to delete during the process.

Steps to Reproduce

1. Go into the Admin CP.
2. Click on "Appearance".
3. Under the "Colors" section, clear the first input textbox.
4. Start typing a pound symbol followed by a sequence of numbers or lowercase letters such as #333 or #aaa.
5. Hit backspace while at the end of the text input within the textbox.

Expected Behavior

The ColorInput textboxes in Flarum should not automatically complete the hex input text, especially when you want to add hex code that is non-sequential in letters or numbers.
