@yusuf-musleh Looks good 👍

• I tested this: I followed the testing instructions and I verified that the counts are updated when tags changed
• I read through the code and considered the security, stability and performance implications of the changes.
• I tested that the UI can be used with a keyboard only (tab order, keyboard controls).
