Short description

Opening the context-menu via right-clicking adds an entry to the list returned by plotItem.vb.menu.actions(). Tbh this behaviour didn't lead to complications for me, but I don't think it should behave like this.

Code to reproduce

In REPL

import pyqtgraph as pg

p = pg.plot([1,2,3,[4,5,6])
len(p.plotItem.vb.menu.actions()) # = 4
# now right-click in plot window
len(p.plotItem.vb.menu.actions()) # = 7
# now right-click in plot window
len(p.plotItem.vb.menu.actions()) # = 8
# repeated right clicking and evaluation of len(...) shows always + 1

Expected behavior

After first right-click, the actions-list should be constant (at 7 in this case).

Tested environment(s)

• PyQtGraph version: 0.12.4
• Qt Python binding: PyQt6 6.3.0 Qt 6.3.0
• Python version: 3.9.2

Additional context

It might be due to what GraphicsScene.addParentContextMenus is doing:

BTW: the reason I came to this was, because I wanted to remove some of the entries of the contextmenu, as they don't work with the data I am plotting (different points have different brushes which clashes with some plot options).
