Description

From this #3084
Its seem like I can replace or remove any parts of url with $uritransform, so I create this rule

||pantip.com^$doc,uritransform=/#lead:.*//

to remove tracking part of

https://pantip.com/topic/41624586#lead:related:6B9mGrzkxFdzAeuBEWJhXs:6:https://pantip.com/topic/42521369

(example url) but it works when there is only this uritransform rule enable. When I enable another uritransform rule:

*$uritransform=/\?fbclid=//

Both uritransform rules stop working, and uBO doesn't mark any rules as invalid too. If the second rule is invalid, the first rule should still working.

A specific URL where the issue occurs.

`https://pantip.com/topic/41624586#lead:related:6B9mGrzkxFdzAeuBEWJhXs:6:https://pantip.com/topic/42521369`

Steps to Reproduce

1. Create test.txt file in Desktop
2. Allow uBO to access to file URLs
   
3. Import test.txt to uBO custom filters and add file:/// in trustedListPrefixes to make sure this filter have enough permission.
   
4. Disable all filters beside test.txt to make sure test.txt rules don't conflict with other rules.
5. Add ||pantip.com^$doc,uritransform=/#lead:.*// rule to test.txt
6. Add *$uritransform=/\?fbclid=// rule to test.txt
7. Save test.txt
8. Click update filter
   
9. go to https://pantip.com/topic/41624586#lead:related:6B9mGrzkxFdzAeuBEWJhXs:6:https://pantip.com/topic/42521369 site
10. see ||pantip.com^$doc,uritransform=/#lead:.*// doesn't work

Expected behavior

1. ||pantip.com^$doc,uritransform=/#lead:.*// should work even there is *$uritransform=/\?fbclid=// rule.
2. tracking part of url should be removed and remain only https://pantip.com/topic/41624586.

Actual behavior

||pantip.com^$doc,uritransform=/#lead:.*// doesn't work and browser go to https://pantip.com/topic/41624586#lead:related:6B9mGrzkxFdzAeuBEWJhXs:6:https://pantip.com/topic/42521369 when there is *$uritransform=/\?fbclid=// rule.
