Here’s a video of how this bug works.
First I show how it’s usually supposed to work. But then when I try to type " | " sign , it for some reason multiplies the “Replace with” message 3-4 times.
However, it’s only a visual bug. If you confirm replacing the message, in script it doesn’t multiply the message and only replaces once.
(Could actually multiply up to 6 times , I tried to see if it would happen , but unfortunaly didn’t happen on recording)
