Context menus are offset when opened close to the right edge of the screen

Issue type

UI bug (incorrect info or interface appearance)

Description with steps to reproduce

When right-clicking to bring up a context menu, the menu should open with its top left corner at the mouse position. This works in most cases but beyond a certain threshold (close to the right edge of the screen) the menu will "snap" to the right edge of the screen.

This also affects the "page view" menu, which is also snapping to the right edge of the screen.

Task

If there is not room for the context menu to appear to the right of cursor's position, it should appear to the left instead, like this:

The context menu may still spill out over the right edge the MSS window if there is enough space on the screen for it to appear:

In which versions of MuseScore Studio is this issue present?

latest nightly

Regression

No.

Tested on macOS, but likely present on other systems

Additional context

Discovered while working on #33867 - the culprit is (at least partially) the movePos call that takes place inside the conditional that was changed in that PR.

I traced this on current main. The positioning code now lives in the pinned muse_framework submodule, and the non-cascade overflow branch still clamps the menu against the screen edge instead of placing it on the cursor's left. I found no open PR referencing this issue and am working on a focused fix in MenuView::updateGeometry().

[aribradshaw]

Draft fix is now available in musescore/muse_framework#229. It replaces the right-edge clamp with left-of-cursor positioning for top-level menus. The changed file passes the framework's pinned Uncrustify configuration; consumer-app CI is requested on the draft PR.
