Monaco Editor Playground Code

Reproduction Steps

1. Open the Monaco editor playground.
2. Don't change the default values. Set the CSS to body {direction:rtl}.

Actual (Problematic) Behavior

The editor disappears (apparently rendered beyond the viewport).

Expected Behavior

The editor should remain visible and usable. It should probably remain LTR even when the rest of the page is RTL.

Additional Context

Manually adding direction: ltr to the CSS of the container div seems to fix it.

I found a past issues that might help find a good fix https://github.com/microsoft/monaco-editor/issues/4141

IMPORTANT: This isn't a request to add RTL support to the editor. It's a request to make the editor work (in LTR direction) when embedded in an RTL page, without needing any additional hacks.

Thanks! :)

Start by reproducing the problem in the linked Monaco Editor Playground with body {direction:rtl} and compare it with the workaround that adds direction: ltr to the container. Read the related issue #4141 for context, then trace the editor container's layout behavior. Done means the editor remains visible and usable inside an RTL page without an external CSS hack; verify the playground reproduction.
