Sprint picker won't suggest all the future Sprint names in issue screen

Issue Summary

The Sprint field picker on the issue edit/view screen won't show all the available Sprint names if the future Sprints are created with more than 9 numerical sequences.

Also, the Sprint field won't allow the manual update of the Sprint name. Especially, the Sprint name with the single-digit won't be shown in the suggestion.

Steps to Reproduce

• Create Sprint on any board with a pattern like:
  • "TT Sprint 3", "TT Sprint 30", "TT Sprint 31", "TT Sprint 31"....."TT Sprint 38".

• The Sprint field picker on the issue view screen would hide the "TT Sprint 3" once the "TT Sprint 38" is created.

Expected Results

The Sprint picker should show all the matching suggestions and allow the user to choose any sprint name.

Actual Results

The Sprint name with the single-digit won't be shown. Eventually, the user can't select the desired sprint. The scroll option also won't show the Sprint name.

Workaround

• Delete a few of the future sprints if there are no issues tagged to them.
• Or, update the Sprint using the bulk update option.
