Allow multiple PR description open at once

[opiation]

I searched for issues like this but the only similar feature request I could find was #2853 which seems specific to PRs of a single branch.

I would like to have an editor open for each open PR that I have. I commonly use this workflow with the GitHub web site opening each of my PRs in separate tabs functioning as a sort of task list for things I should keep an eye on. This seems impossible with the pull request extension. If a pull request description is already open in a VS Code editor, that existing editor is reused for the next PR I select instead of opening the next PR in a new editor.

For disambiguation:

• By open, I mean Open Pull Request Description to the Side
• By editor, I mean a tab in VS Code, not VS Code itself

If this feature is supposed to be supported, then consider this a bug report.
