Resolves: #21480

Creating tuplets from a selection outside note input (e.g. Cmd+3) now leaves a predictable selection.

Before

• A range selection was lost. Only one note or rest stayed selected, so you had to reselect the music for the next step.
• Which element stayed selected depended on the order in which the elements had been created, not on their position in the score. For a bar of quarter notes turned into triplets, the selection could end up on any of the new rests.
• A single note and a single rest gave different results: from a note, the rest after it was selected; from a rest, the first rest of the tuplet.

After

Selected before	Selected after
Range (one or more bars, one or more staves)	The same range
A single note or rest	The first note or rest of the new tuplet
A list (e.g. Cmd+click on several notes)	The first note or rest of the first new tuplet in the score

If the first element is a chord, the whole chord is selected.

A range stays a range, as it does when you change the duration of a range. You can then go on working on the same music, for example by transposing it or making another tuplet. For a single element or a list, the first element of the tuplet is where you would usually start filling it in: pressing N starts note input there, with the tuplet's note value.

Creating a tuplet during note input is unchanged.

Demo

1. Enter four quarter notes in a bar, select the bar and press Cmd+3. The bar stays selected.
2. Undo, click the first note and press Cmd+3. That note is selected, not the rest after it.
3. Undo, Cmd+click the third and then the first note, and press Cmd+3. Only the first note is selected.

This looks good to me @davidstephengrant, very nice! Shall we pass to @miiizen for code review and then QA after if you're happy with it?

@avvvvve Sounds good, let's do it!

📝 Walkthrough

The tuplet operation now sorts selected chord rests by tick and track before insertion. It retains the existing exclusions and base-length calculation. After insertion, it restores range selections or selects the first created tuplet’s elements. It also updates note-input duration to the first tuplet’s base length.

Merge Risk: 🔵 Low · up to 3841a

Creating a tuplet from a backward range can make the next selection extension move the wrong boundary. This is a bounded interaction issue, but the active edge should be preserved.

Explanation

Issue #21480 requires predictable selection after tuplets are created outside note input. In NotationInteraction::addTupletToSelectedChordRests, the change orders selected chord rests by tick and track, preserves and restores range selection boundaries, and selects the first element of the first created tuplet for non-range selections. It selects all notes when that element is a chord. The change also sets the input duration from the created tuplet base length. These behaviors match the PR intent for range, single-element, list, and chord selections.

Full details: Out of Scope Changes check

Explanation

The diff changes only tuplets and selection handling in NotationInteraction::addTupletToSelectedChordRests. Sorting the processed elements, restoring range state, selecting the first tuplet element, and updating the tuplet input duration directly support issue #21480 and the stated PR behavior. No unrelated change is shown.

around the range rebuild in the code containing setRangeTicks() and
