Issue Summary

Using an If block having an advanced compare with regular expression fails to match string values if they contain special characters.

Steps to Reproduce

1. Create a rule
2. Add an if block with advanced compare conditions to match a custom field if the value is equivalent to any one of the regular expression values.
3. 
4. Create an issue, and set this customfield to a value that exists in the regular expressions that have a value with brackets.

Expected Results

• The condition should match based on the rule and any brackets should be auto escaped

Actual Results

• The conditions don't match because the value selected in this case has brackets which are not seen as a literal bracket.

Workaround

You can escape those special characters to ensure that the regular expression is matched with the rule.
