Sometimes the lazy value placeholder shows up

[weinand]

Testing #143572

Sometimes the lazy value placeholder shows up and I cannot get rid of it:

Even stopping and restarting the debug session doesn't help. I have to restart VS Code.

I can reliably reproduce this by setting the variables value (see #143751). From that moment the "lazy var" is sticky and I need to restart VS Code to get rid of it.

Yes, easy repro in js-debug:

1. Have a getter with a setter. Double click to set the variable and just click out
2. Enter anything in the repl (to trigger a variable refresh)
3. The variable now includes its placeholder and (...). It should remain expanded.

Dupe of #143751. The DOM gets messed up permanently
