When Discussion Tools (specifically the Reply tool) is used to add the template {{Section resolved|1=~~~~}}, it does not detect the signature and skip adding one (intended functionality), but instead duplicates it.
**Steps to reproduce**
# Go to https://commons.wikimedia.org/wiki/Commons:Bots/Work_requests with Microsoft Edge Dev version 92.0.884.2, on Windows 10 version 20H2
# Make sure you are logged in with New Vector as the skin
# Under any section, click on "Reply" for any of the comments
# In the editing area, paste in {{Section resolved|1=~~~~}}
# Click "Reply"
**Actual results**
The signature is duplicated. See diffs [[https://commons.wikimedia.org/w/index.php?title=Commons:Bots/Work_requests&type=revision&diff=560974581&oldid=560970984&diffmode=source|1]], [[https://commons.wikimedia.org/w/index.php?title=Commons:Bots/Work_requests&diff=prev&oldid=560970952&diffmode=source|2]], [[https://commons.wikimedia.org/w/index.php?title=Commons:Bots/Work_requests&diff=prev&oldid=560946839&diffmode=source|3]], [[https://commons.wikimedia.org/w/index.php?title=Commons:Bots/Work_requests&diff=prev&oldid=560946752&diffmode=source|4]], [[https://commons.wikimedia.org/w/index.php?title=Commons:Bots/Work_requests&diff=prev&oldid=560946735&diffmode=source|5]], [[https://commons.wikimedia.org/w/index.php?title=Commons:Bots/Work_requests&diff=prev&oldid=560946700&diffmode=source|6]], [[https://commons.wikimedia.org/w/index.php?title=Commons:Bots/Work_requests&diff=prev&oldid=560946550&diffmode=source|7]], and [[https://commons.wikimedia.org/w/index.php?title=Commons:Bots/Work_requests&diff=prev&oldid=560944988&diffmode=source|8]].
**Expected results**
Reply tool detects the signature, and skips adding a duplicate one.
