🐛 Cannot escape forward slash in RegEx

[MarcusOtter]

Describe the bug

In a title regex, you can not match / by escaping it like this \/ because we just check for 2 slashes to find a regex.

Steps to reproduce the bug

1. Write a regex like /he\/him/
2. Only he gets matched

Expected behavior

he/him should get matched

[MarcusOtter]

As a workaround, one can use [\x2F] in place of \/ and it should work.

e.g /he[\x2F]him/
