Incorrect Behavior When Pinning a File While Another File is Already Pinned in Preview Mode.

[hillesa]

Type: Bug

Description:

When attempting to pin a new file while another file is already pinned and open in preview mode, the new file incorrectly replaces the pinned file instead of opening in the regular mode. This leads to inconvenience as the previously pinned file is lost.

Steps to Reproduce:

Open a file, for example, some-file.md.
Pin this file by clicking on the pin icon next to the file name.
Open another file, for example, another-file.md, using the "Open Preview" command.
Observe that instead of opening another-file.md in preview mode, it opens and replaces the previously pinned file some-file.md.

Expected Behavior:

When opening a file using "Open Preview" while a file is already pinned, the new file should open in preview mode without replacing the pinned file. The pinned file should remain pinned and open.

Actual Behavior:

The new file opened using "Open Preview" replaces the previously pinned file.

@hillesa I am having trouble following along, for example what is the "Open Preview" command, are you maybe using an extension? Maybe you could share a screen recording or screenshots.

I believe this is an explicit decision by markdown to only have 1 preview editor overall, but not sure.

Yes, I could think about it too if it was only about opening for viewing! But here we are talking about pinning! That is, I pin one file it should not change until I unpin it myself. You understand me
