Add a warning for the JQL that exceeded the max length of 255 in Card colours

Problem Definition

If you add a JQL that is more than 255 in length will result in that JQL to not be added. However, that is no warning presented to the user that their JQL exceeded the length.

Suggested Solution

Add a warning to tell the user that the JQL is not added with the reason of why it is not added.

Why this is important

This is important so that users know that their JQL is not added and why this limitation.

Workaround

You can create normal Issue Filters with your JQL and then join them:

 
filter = "Filter for BBB" AND filter = "Filter for BBB 2" 

This way you can spread the JQL across multiple JQL.
