LiveTable filter fails for dotted usernames

Live Data serializes the users mailadress as an escaped XWiki document reference, but
the LiveTable backend appears to compare that escaped serialization directly
with XWikiDocument.creator → XWiki.foo@domain.com not equal to XWiki.foo@domain\.com

XWiki version:
17.10.4

Example Macro:

{{liveData
id="troubleshootingguide"
source="liveTable"
properties="doc.title,error-message,doc.creationDate,doc.date,doc.creator,tags"
sourceParameters="translationPrefix=Customization.&className=Customization.TroubleshootingEntryClass&tags_class=XWiki.TagClass"
}}

Steps to reproduce:

1. Create an entry with creator XWiki.devops.
2. Create another entry with creator XWiki.foo@domain.com.
3. Filter the doc.creator column.

Actual result:

Filtering for XWiki.devops works.

Filtering for the email-based user returns no results.

XWiki.foo@domain.com

Expected result:

The filter should match the documents created by XWiki.foo@domain.com.
