Can't use share button because everything freezes as soon as above filter is added.
**Expected behavior**
All of the software should not freeze. If there some issue with ignore text or with the URL/website, it should not impact complete software.

**Additional context**
Note that above filter was added as global filter to thousands of watches but this issue is only with this one URL. It took us a while to zero down to this one URL.
