Footnote number still shows as tracked change even after 'show track changes' is disabled

Steps:

Create a new Writer doc.
Enable ‘record track changes’ and ‘show track changes’.
Insert a footnote with Ctrl-T.
Add some footnote text.
Disable ‘show track changes’.

For me, all tracked changes now lose their underlines and revert to the default colouring except the footnote number (meaning the number at the start of the footnote line, not the number/reference in the body of the text), which is still coloured and underlined.

But I’d expect the footnote number to revert to default appearance, the same as the other tracked changes.

Presumably what I’m seeing is not the intended behavior. Can anyone reproduce it?
