Opening a Playground’s bindings signals MessageNotUnderstood

[Rinzwind]

In Pharo 13 build 504, after doing n := 1 in a Playground, opening its bindings signals a MessageNotUnderstood (“Instance of SmallInteger did not understand #windowTitle”).

I checked earlier builds: a MessageNotUnderstood is signaled in build 465, but not in build 464. The reference commits for these builds are given below (listed using the snippet given in issue #17163). This issue seems most likely to be due to the changes in Spec commit 8c6e6f0291 or NewTools commit 612a06e542 by @Ducasse.

Oops it should probably be my mistake. I will have a look

[Ducasse]

Probably

StInspectorPresenter >> windowTitle
	^ self model windowTitle
	
	^ self model ifNotNil: [ :m | m windowTitle ] ifNil: [ 'Inspector']

Now I put

StInspectorPresenter >> windowTitle
	
	^ self model ifNotNil: [ :m | m printString ] ifNil: [ 'Inspector']

and it seems to work.
Having title on SmallInteger did not make that much sense to me.

OK, but now the window title when inspecting String loremIpsum is (build 511):

Whereas before it was (build 506):
