FileSystemProvider: Switching file in the editor causes explorer incomplete sync

[plus-]

Version: 1.34.0 (user setup)
Commit: a622c65
Date: 2019-05-15T21:59:37.030Z
Electron: 3.1.8
Chrome: 66.0.3359.181
Node.js: 10.2.0
V8: 6.6.346.32
OS: Windows_NT x64 10.0.17134

Steps to Reproduce:

1. Implement a remote FileSystemProvider
2. In the explorer browse and open 2 different files Apple & Banana
   Apple uri is like so scheme:/path/to/Apple
3. After opening Banana go back to Apple from the editor title
4. The explorer will update without the children from the top parent folder containing Apple (in above example path will be empty). All other folders still have their children.
5. Also the "Refresh Explorer" button doesn't load that folder children.
6. Closing all files from that folder in the editor will fix the previous issue.

It may be related to the logic behind highlightning the current file in the explorer.

I'm reopening this as I though it was an issue on my side but I have more information.

It happens only for the first folder defined in the vscode workspace, other folders works fine (although the current file is not highlighted in the explorer). If I switch around the remote filesystem in the workspace the issue is always happening on the first one defined.

I've checked the debugger and it only calls readDirectory for the first folder of the workspace when switching files in the editor.

You can test for yourself on this branch https://github.com/plus-/vscode-cmis/tree/sync-error
I've trimmed down the extension to the minimum

And open the following workspace (it just has one remote folder for simplicity but since the problem only happen on the first folder it's ok)

{
	"folders": [
		{
			"name": "Alfresco",
			"uri": "cmis://admin:admin@cmis.alfresco.com?ssl=1&base=cmisbrowser"
		}
	]
}

when you expand the parent remote folder, at the top there is a __vscode_example folder with some files (apple and banana) if you switch between them you will see the problem (it's not immediate as the operation is async).

Got it. Looks like a duplicate of #73469
If you F1 > developer tools > console
Do you see some errors?

No errors in the console.

I've noticed the bug still exist in the VSCode Insiders version. Switching tabs remove the opened folder from the explorer like before, however now the refresh sometimes works (about half the time), the opened folder will reappear.
