Files stop working when renamed from *.excalidraw to *.excalidraw.svg and vice versa

Description

When an excalidraw file is renamed to another supported extension (e.g. from *.excalidraw to *.excalidraw.svg and vice versa) the file can not be opened by the excalidraw plugin anymore. It only shows a blank VSCode when opening the file.

Steps to reproduce

1. Create a file with the supported extension (e.g. test.excalidraw)
2. Optionally add some graphs to the file
3. Rename the file to test.excalidraw.svg
4. Close and open the renamed file

Expected behavior

Renaming the extension to another supported extension should not render the file unusable by VSCode.

Workaround

1. Create a new file with the required extension
2. Copy and paste the contents from the old file to the new file

Ok I have a naive but working solution (basically I try to load the file as a json/png/svg sequentially).

I agree that it it feels really good to be able to change the filetype by renaming the file 😃
