Note: This is implemented in a very hacky and one-off manner. The primary change is to pass a rem size through the markdown render tree, and scale all sizing (rems & pixels) based on the passed in rem size manually. This required copying in the `CheckBox` component from `ui::CheckBox` to make it use the manual rem scaling without modifying the `CheckBox` implementation directly as it is used elsewhere. A better solution is required, likely involving `window.with_rem_size` and/or _actual_ `em` units that allow text-size-relative scaling. Release Notes: - Made it so Markdown preview uses the _buffer_ font size instead of the _ui_ font size. --------- Co-authored-by: Ben Kunkle <ben@zed.dev> Co-authored-by: Nate Butler <nate@zed.dev>
