'$' sign gets ignored on bulk remap

[rbosker]

Describe the bug
'$' sign gets ignored on bulk remap, which is probably due to the introduction of w3c spec.

To Reproduce
Steps to reproduce the behavior:

1. Bulk remap a token, where the token name contains a $ sign.
2. try to remap to another name
3. the '$' sign gets ignored and remap is not done

Expected behavior
Be able to remap tokens containing a '$' sign

This is due to regex. Users can escape the $ by typing \$

we should make regex a toggle though

Sounds like this is a known issue that needs to be added to technical docs and in product messaging. @rbosker what do you think?

We are also blocking the ability to have $ in the token name as it is forbidden so this should be a non-issue in the near future.
