Removing Instrument Name in Staff/Part Properties changes clef from Bass to Treble

Related issues:

• Clef changes after remove treble staff 333278
• Clef change at start of score converted to mid-measure on save/reload with modified system barline 292790
• single piano stave with bass clef turns to treble after property edit 272255

I have a piano duet score with the second instrument only showing the bass part.

I need to hide the instrument name (the whole score if for piano only, so it's redundant).

• Right click the second instrument.
• Select the Staff/Part Properties pop-up dialog
• Clear the Long and / or Short Instrument Name
• Click Apply

Observe:

• the instrument clef changes from bass to treble and moves down one octave.

Note: if you do the same clearing of instrument name in the Instruments panel, there is no issue.
