GitLens cannot show file changes from an interactive rebase todo

[Chudesnov]

Description

When using VSCode as the editor for interactive rebase (git rebase -i), commands like "open changes" when activated from a commit details side panel spawned by clicking on a commit hash inside an interactive rebase preview (/path/to/repo/.git/worktrees/worktree-name/rebase-merge/git-rebase-todo), often fail, producing errors like:

Open File - Unable to open "relative/path"
Unable to open working file. File could not be found in the working tree

When they do work, the path displayed for the file at relative/path matches the main worktree (/path/to/repo/...) rather than the current worktree (/path/to/worktree/...), unlike when "Open changes with previous revision" is called from the context of an editor with the working directory inside the worktree (/path/to/worktree/relative/)

Looks like it might be caused by incorrectly identified worktree paths when opening git-rebase-todo, see the console output below.

Expected behavior

Instead of using the /path/to/repo/.git/worktrees/worktree-name/rebase-merge/ path inferred from the location of the git-rebase-todo file and trying to get the worktree location using rev-parse --show-toplevel, it should either explicitly use the path from .git/worktrees/worktree-name/gitdir or use a different mechanism that doesn't rely on the working directory being outside of .git.
