Regex works on test site but not on "ignore text" filter

[b4bbuilder]

Describe the bug
Regex which works on regex101.com does not work on the ignore text filter.

Version
0.40.0.4

Steps to reproduce the behavior:

1. Go to mercari.com
2. Enter any search that results in a few results which will create an "Items related to" section
3. Input any other the following regex in the "ignore text" filter
4. View "Show current snapshot"

/(?<=Items)(?s)(.*$)/
/Items(.*\n)+/
(https://regex101.com/r/B8vMuJ/1)

Expected behavior
All text following that specified in the regex including new lines being ignored. In the above examples "Items", included or otherwise, should be ignored and everything that is displayed beneath it. The third example starts at a specified string and ends at another. My goal is to ignore the "Items related to" section.

Desktop (please complete the following information):

• OS: Ubuntu v.22.04
