0.45.14-0.46.2 can't find vscode extensions (workaround found)

I try to find Dev Containers extension in Marketplace, but it is not even listed:

interestingly, the very same binary cursor-0.45.14x86_64.AppImage on another my machine finds Dev Containers extension:

I am wondering why can’t it find the extension.

WORKAROUND: i opened vanilla vscode, successfully found and installed Dev Containers, then I started again Cursor, went to the extension installation tab and there was a clickable text message “Click to import all local VS Code extensions” (seen on the first screenshot) – this fixed the problem.
However the clickable text message disappeared now, so, i guess we could run it like this now:

P.S. Confusingly, on both machines the binary cursor-0.45.14x86_64.AppImage reports it has version 0.46.2

Hey, that’s strange because it’s accessible for me. What happens if you enter this link in your browser and open it in Cursor? Will it open the extension you need?

cursor:extension/ms-vscode-remote.remote-containers

i can’t open it in browser, not a valid URL.
CTRL-P (or F1) command pallete in Cursor also not recognizing this.
In marketplace search dialog also nothing:
