The time format of the date fields on Issue search does not respect the "Look and feel" settings or locale selection

Issue Summary

We had an announcement that the format of date/time picker fields in Jira will not be defined in the Look and feel anymore, but by the language selected for each user (See JRACLOUD-68381). However, there are some sites where the time format of the date fields/columns in the issue navigator section neither respect the "look and feel" settings or the language selected, displaying an arbitrary format (MMM, dd yyyy hh:mm a) which does not seem to be defined by any logic way.

Steps to Reproduce

1. Navigate to Settings > System > Look and feel
2. Ensure the date format is the default (dd/MMM/yy)
3. Ensure the Date/time format is the default (dd/MMM/yy h:mm a)
4. Select the language "English UK" in your personal settings
5. Navigate to the global issue navigator
6. Using the List view, select a date/time picker field to be displayed as a column

Expected Results

The format of the date/time fields/columns of the view should be displayed in the format related to the language selected (dd MMM yyyy, hh:mm), just like it works for the issue view.

Actual Results

The format displayed is "MMM, dd yyyy hh:mm a":

Workaround

None so far.
