Cannot use PDF Preview with Latex Workshop: Tries to resolve some webview subdomain

[MexHigh]

Bug Description:

I have Latex Workshop installed and working perfectly, only the webview does not work. It tries to resolve to a <uuid>.webview.<theia host> subdomain which i don't have A or AAAA records for.
This does not only apply to Latex previews, but for normal PDF files too (as long as I don't rightclick --> open with --> preview. This does work and opens my browsers default pdf viewer.)

Just removed some personal information :)
I'm hosting Theia on my own infrastructure for private use. I'm using the caddy webserver as a tls reverse proxy but this error occures even if i bypass it.

Steps to Reproduce:

1. Installed Latex Workshop via vsix
2. Opened a .tex file
3. Clicked on the preview button over the editor on the right
4. Choose "in VSCode tab"

Additional Information

• Operating System: Ubuntu Server LTS 18.04
• Theia Version: In a selfmade Docker container (parent image: ubuntu:18.04, using the same package.json as in https://github.com/theia-ide/theia-apps/blob/master/theia-full-docker/latest.package.json, only added latex-workshop to the theiaPlugins key, but this error occures without the change with normale PDFs as well)

What do i have to do to suppress theia to use those generated subdomains? I've read about the THEIA_WEBVIEW_EXTERNAL_ENDPOINT envvar but I don't quite get what it is used for. If i set it to the same domain theia is running, the webview tries to resolve to localhost with some high port instead which does not work either.

I also encountered this problem, have you made any progress?
