By the way, thanks for the "coop_widget" , it works great!

I'm glade you like it.

Can you shortly explain the steps to reproduce the error?

[Adancurusul]

I just click the “Show Preview” in Vscode


And then the question arose.

[FloVanGH]

Thank you. I can reproduce it. At @hunger can you take a look?

I can reproduce the issue and this is the backtrace I see:

Looks like yet another issue with the ComponentContainer needing information from the embedded component:-(

[ogoffart]

Is it the same as #3989 ?

(That the layout constraints depends on the window size)

[ogoffart]

This should be fixed in the nightly version of the extension (same as #3989)
Please re-open if the problem persist
