Browsing implementors/senders from source code editors doesn't browse expected selector

[sonibla]

Bug description In the screen recording, I want to browse implementors of #readParametersFromContext:, but Pharo instead looks for #prepareNewCommand:readParametersFromContext: (which doesn't exist) It works when explicitly selecting the selector, but it shouldn't be needed

To Reproduce

1. Create CmdMenuGroup1, subclass of CmdMenuGroup
2. On class side, define

sourceCodeMenuActivation

	<classAnnotation>
	^ SycSourceCodeMenuActivation
		  byItemOf: ClyQueryMenuGroup
		  for: ClySourceCodeContext

4. Right click in a source code editor > debug

Version information:

• OS: Windows/Linux
• Version: Pharo-11.0.0+build.95.sha.554b538cd430662e26bd8ae330e02a5743283451 (64 Bit) (and pharo 10)

Interestingly it works if I used they shortcuts (cmd m). And after that it even works via the menu.

Maybe the error leads to some initialisation not done correctly for the menu?
