Bug Description:

I tried to use latest Python extension for Visual Studio Code. For this moment it's 2020.5.86806.
But got some issues during the initialization and as a result latest python extension doesn't work with theia:

Same as #7999 or #3186 (comment)?

No available file system provider for schema file

Here is the WIP PR for the VS Code FS API: #7908

[akosyakov]

First issue is tracked in #6636. Second issue is new. The last is being worked on in #7908.

I've updated the description with the corresponding issues.
We (at Red Hat) are going to start working on CustomEditor API #6636

[azatsarynnyy]

Cannot read property 'Web' of undefined

this one should be fixed by #8038

[nickboldt]

When do we think this will be fixed? Looking for a Che milestone so we can map that to a CRW release. Ideally, Che-theia 7.20, if possible?

[azatsarynnyy]

I updated the description with these two API already implemented:

• UIKind API - Cannot read property 'Web' of undefined
• vscode.workspace.fs API - No available file system provider for schema file

Unsupported activation events

About this one, I haven't seen it when I was trying the plugin here #3186 (comment)

[djmaze]

As the CustomEditor API is now implemented, does the extension now work?

Hello @djmaze, when I tried it here it was working well. In Google Chrome at least.

I'm closing this one. Feel free to reopen if more work should be done here.
