VS Code Extension: Preview ignores `output-dir` in `_quarto.yml`

[roland-KA]

Until recently the VS Code Extension put the files it generated for a preview (for revealjs) in the directory which I specified in _quarto.yml in output-dir.

Now this behaviour changed:

• the extension ignores the value in output-dir
• it creates instead a separate directory with the name MyFile_files for a preview of MyFile.qmd

Is there any way to get the former behaviour back? Is it possible to specify the output directory for the preview explicitly?

I'm using Quarto 1.4.549 and the VS Code Extension v1.110.1

BTW, there is another strange behaviour within this context:

• When I render the whole project (using quarto render --to revealjs) after showing a preview, then the content of the preview window changes and shows the content of output-dir instead of MyFile_files
• But as soon as the "Preview"-button in VS Code is used again, the preview window switches back to the content of MyFiles_files

I think, I've identified the problem more closely. The preview has problems with filenames containing German umlauts.

When previewing a e.g. a file named Einführung.qmd the preview ignores the output-dir and creates a separate directory with the preview files (as described above).

As soon as the file is renamed to Einfuehrug.qmd, everything works fine and the preview puts it's files in the folder specified by output-dir (and it uses in this case also the CSS-file specified for the project; which is the desired behaviour).
