Port TextEditorView and DnDUploader to spina.
Review Request #13115 — Created June 19, 2023 and submitted — Latest diff uploaded
In preparation for integrating the rich text toolbar, this change ports
ourTextEditorViewandDnDUploaderto TypeScript via spina.This also fixes one issue I discovered where if the only thing you've
done with a text editor is upload an image, it won't think the editor is
dirty and so saving discards the contents.
- Ran js-tests.
- Used drag and drop to upload files into a text editor.
