Impossible to use "Add to selection" to select different items at the same time

Issue type

UX/Interaction bug (incorrect behaviour)

Description with steps to reproduce

The handbook has instructions about how to select specific type of objects in a range selection.
• Select a specific range (one or more measures, one or more instruments)
• Right-clic on an element
• Clic on "similar in this range" for a quick selection of only that type on item, or "more" to specify a subtype
• Then, you could want to add another type on item (e.i. you previously selected all dynamics, then you want now to select also the hairpins), and the handbook tells you to use "Add to selection", but this is simply not possibile: any selection of a new item (left clic, right clic, any combo with Ctrl, Shift or Alt) will always delesect your previous selection... and anyway you already have only the items selected, and the range already lost.
Best case scenario, Ctrl+right-clic will retain the already filtered selected items, but the range selection is already lost and the "Add to selection" still appears useless.

Select range

Try "similar in this range" for example for dynamics:

Select an hairpin and "more"

Add to selection:

Only that specific hairpin gets selected (since the range has already been lost):
