🐛💄 milestone progess counter does not update when assigned issue gets deleted

Summary

Deleting an issue from the issue list in the top right corner

results in counter mismatch on assigned milestone. Thus also resulting in wrong progess bar percentage of said milestone.

Steps to reproduce

1. Make sure to have a milestone created already.
2. Create Issue and assign it to a milestone.
3. Delete said issue.
4. Watch the issue counter as well as progress bar on the milestone overview page.

What is the current bug behavior?

Bug behaviour is not refreshing the counter when issues get deleted.

What is the expected correct behavior?

Correct behaviour would be to refresh the counter.

Relevant logs and/or screenshots

There are no relevant logs - this can be reproduced in seconds by anyone.

Possible fixes

I have no idea about implementation as i am only a user.

But I found a workaround: Just reassign the milestone to some other existing issue. This will update the counter.
