Selecting scope in ‘Senders of’ window can signal SubscriptOutOfBounds

[Rinzwind]

Scenario (tested in Pharo 13 build 478):

• In the Scope(s) Editor, add a scope ‘Test’ with the package ‘AI-Algorithms-Graph’
• In a Playground, enter ‘1 printString’ and use ‘Senders of it’ in the context menu’s ‘Code search’ submenu to search for senders of the selector
• In the ‘Senders of’ window, select ‘Test’ in the scopes list (see screenshot below)

A debugger is opened due to the signaling of a SubscriptOutOfBounds (“SubscriptOutOfBounds: 5 in an OrderedCollection(a ClySystemEnvironmentScope(Current image) Test)”).
