Issue Summary

Filters with underscores in the name are not getting listed in the Issue sources while creating plans in the advanced roadmaps.

This is reproducible on Data Center: (yes)

Steps to Reproduce

1. Create a filter name with an underscore in it. For example, ABCD_DEFG_HIJK
2. Now create plan by going under the Plans menu.
3. Select Issue sources as Filter.
4. Search with ABCD_D and you will notice that it doesn't provide any suggestions in the dropdown list. Till the time we type letters before the underscore, the suggestion works but not after it. For example, if you search till ABCD, it will list the filter fine. But this may be very cumbersome if we have a similar prefix with the same letters.

Expected Results

The Issue sources dropdown list should list suggestions for filters with an underscore in the filter name.

Actual Results

It doesn't show any suggestions.

Workaround

A possible workaround is to replace underscores _ with something like a hyphen - and that makes the suggestion works fine.
