Time signature properties should apply to all selected time signatures where possible

Open the attached score in 2.3.2. Click on the Flute time sig.
Result: Only that time signature is selected (as expected).
Open the same file in MS 3.5. Click on the flute time sign.
Result: All time signatures are selected (unexpected). You need to Ctrl + click to select only the one.
Leave the selection as it is. Right click over the Flute time sig. Change the 1/8 note group pattern to 2 per beat (for example).
Result: Despite all the time sigs being selected, the changes only apply to the Flute staff—as expected.
Selection worked as expected in MS 2.3.2, but there has been a regression somewhere in MS3.
