Match Tool is broken - the match button doesn't do anything

[macta]

Bug description Launching the match tool - shows an expression with a pharo code sample - however if you edit it and and your own match expression the match button doesn't nothing (unlike the real rewrite editor tool)

To Reproduce Steps to reproduce the behavior:

1. Open the match tool - add one of the examples from the help
2. click match - nothing happens

Expected behavior I would expect the expression to be evalualtion and problably have some way to express where the epression should be run (like the rewrite editor)

Screenshots If applicable, add screenshots to help explain your problem.

Version information:

• OS: [e.g. iOS]
• Version: [e.g. 1.6.1]
• Pharo Version P12

Expected development cost Probably smallish if you know where to look

Additional context Add any other context about the problem here.

I think the button is working and match results are being returned - however when it inserts values into the matchesList it doesn't update - so there must be some spec change that hasn't been applied (something to cause a refresh?)

I was not able to reproduce this issue in Pharo 13. Could you add some screenshots please?
