GitHub labels filters flickering

Short description:
While looking for ways to contribute, I followed a link from the contribution guide (like the one for "needs: mock-up or user story") and encountered a UI flickering bug.
I observed this bug on both Brave and Edge.

More info:

I have found that there was a PR with these change:
#415

As shown in the recording, when loading a page for a label that contains quotes (like "needs: mock-up or user story"), the issue list (with the "Open" / "Closed" tabs) appears for a moment and then disappears.

I found a PR that seems related to this change: #415

It appears this issue is still present. The fix might be to revert those changes.

However, a better solution may be to change the link format to the one generated by the current GitHub UI, which seems more stable.
https://github.com/AntennaPod/AntennaPod/labels/%22needs:%20mock-up%20or%20user%20story%22
->
https://github.com/AntennaPod/AntennaPod/issues?q=state%3Aopen%20label%3A%22Needs%3A%20Mock-up%20or%20user%20story%22

I can prepare PR.

Additionally clicking in any link on page with this issue trigger Rate limit error:

I can prepare PR.

That would be nice :)
