Rendering bug: jazz lead sheet: A(sus)

In an empty jazz lead sheet, enter a jazz chord that is:

A(sus)

See how the text "sus" is below. This is a reduced example. The real case was "Ab13(sus4)no3" (in this case "4" is superscript but not "sus"). I can think of ways to question writing this notation, but no matter what, it looks like a rendering bug. See attached screenshot. Using MuseScore 3.6.2.

Note, the same occurs with "Ab13sus4no3", so this seems definitely like a rendering bug.
