Display all fields for Columns in Issue Navigator

Despite the changes implemented in JRASERVER-59412 if the user has a great number of fields with similar names, it might still have issues finding the desired Custom Field. This also affects users who use a screen reader.

For example, having ˜50 Custom Fields with "Component" in the name.

Actual Behavior

Searching by "Component" only

With that, it seems that the limit is reached and the message "26 more options. Continue typing to refine further" is displayed.

Searching by "Component Test 3"

Since we are using a more specific filter, all those options containing Component Test 3 are displayed as expected and the Continue typing message is not displayed.

Desired Behavior

It would be good to have a clickable option to "Show all options" or an incremental option "Show # more choices" message until all choices are visible.
