Current Behavior

I'm attempting to insert the current year into the title of a result as a workaround for Radarr refusing to support sports.

My indexer definition looks like this:

title-0:
  selector: div.tt-name > a[href^="/"]
  filters:
    - name: strdump
title-1:
  text: "{{ .Result.title-0 }}"
  filters:
    - name: re_replace
      args: ["(?i)({{.Query.Keywords}})","{{ .Query.Keywords }} ({{ .Today.Year }})"]
    - name: strdump
title-2:
  text: "{{ .Result.title-1 }}"
  filters:
    - name: re_replace
      args: ["WWE WrestleMania 42 Saturday","{{ .Query.Keywords }} ({{ .Today.Year }})"]
    - name: strdump
title:
  text: "{{ .Result.title-2 }}"

As you will see in the logs, title-0 and title-1 are identical, as re_replace fails to match. But on title-2 the match is successful using literal text instead of a variable.

I cannot tell if re_replace does not support variables in the pattern or if theres some whitespace mismatch between what .Query.Keywords supplies to re_replace and what it prints using strdump.

Expected Behavior

I expect re_replace to support variables in either argument.

Steps To Reproduce

1. Edit any indexer definition to have a re_replace filter with .Query.Keywords as the pattern
2. Perform a search on that indexer
