Header in "Assigned to me" gadget is specially focussed on priority field.

Issue Summary

This is reproducible on Data Center: yes

This problem is reproducible in Jira Data Center ver 9.12.5 and 9.12.6 but not in 9.4.19.

Steps to Reproduce

1. Step 1 : Create a Jira Data Center 9.12.6 setup.
2. Step 2 : Add a Dashboard, let say "Test Dashboard".
3. Step 3 : Now add gadget "Assigned to Me". We can just have default configuration. Nothing to change as such while adding gadget.
4. Step 4 : Check the Gadget header, there is a blue line box around priority header. If we press tab button than focus(blue box) moves to different column.
5. Step 5 : No header should be selected by default.

Expected Results

By default, the focus should not be active (no box) on Priority column header.

Actual Results

Priority column header is by default focussed with blue color box.

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
