• VSCode Version: 1.44.2
• Local OS Version: Windows 7 / 10
• Remote OS Version: RHEL 7.7
• Remote Extension/Connection Type: SSH

Steps to Reproduce:

This is rather a specific issue - currently in my extension I open a diff editor, but in order to provide context commands for that editor, I also need to have some additional information about the diff / file for use in the context menu items. I've done this by encoding that additional information in the query portion of the URI for the right hand diff.

This works ok locally, but in remote-SSH the query parameters disappear so I can't get that information back when running the context commands

I suspect that it's presumably rewriting URIs into vscode-remote:// URIs and back again, and losing the query params in the process.

It also works ok for non file: URIs as they presumably are not rewritten

Possibly I "shouldn't" be encoding params into file: URIs but I haven't yet found a better way to store this context reliably

edit: I've spotted some other problems with using query params on file URIs (cpp extension causes errors, editor windows are out of sync when not saved) and I've discovered another way of doing almost all of what I need, using the isInDiffEditor and isInRightDiffEditor contexts, so I think I'm going to rework this part of my extension to avoid doing this. But I'll leave this here for now as it may be something you want to look into?

1. Write an extension that:
   1. Opens a file: URI including a non-empty query string in the editor.
   2. Adds a context item to the editor title menu that logs the URI passed in to the command
2. Open the file with query parameters and click said button
3. Observe that the query parameters are not present in the URI

Does this issue occur when you try this locally?: No
Does this issue occur when you try this locally and all extensions are disabled?: No
