Svelte Language Tools broken

[jacob-8]

Bug description

When starting an example workspace using the SvelteKit example from https://www.gitpod.io/#get-started, I receive two VSCode messages: Couldn't start client Svelte and vscode.languages.registerDocumentSemanticTokensProvider is not a function

The features of the Svelte for VS Code language tools extension don't work as a result.

Steps to reproduce

Create a new SvelteKit example workspace and watch for the messages in the lower right corner.

Expected behavior

Svelte for VS Code language tools should work (commands like Format Document inside of a .svelte file)

Example repository

No response

Anything else?

If I uninstall Svelte for VS Code (listed currently as v104.9.1) for the project, close the tab (but not the workspace) then re-open the workspace from the dashboard, I notice that Svelte for VS Code is no longer in the "Installed for this project" but is now listed in "Installed for " in the Extensions pane and it works fine. Note that it says v.101.1.1 when going this route.

Not sure if the changes to the extension to support ESM described in sveltejs/language-tools#930 are relevant.

Hi, thanks for reporting that 🙏 ! I can't reproduce that unfortunately, I'm surprised v.101.1.1 works as it was released on Jul 8, 2020. Looking at the changelog, I see v.104.9.0 added support for ESM configs so that should be ok.

I wonder if there may have been a temporary issue, although I see you reported that a few minutes ago and I tested not long after you opened the issue. Please let me know if you continue to see this issue, I will be back in the morning and re-test again with a few new workspaces on my end to see if I can reproduce it.

Sorry, I logged in to Gitpod a year ago and so my settings defaulted to Theia and evidently I also had an old version of that extension installed. Consider giving users who haven't logged in recently a notice that they can switch to VS Code if they are defaulted to Theia??
