The completion popup now behaves now much more as expected than before for the raw textarea: - You can press <kbd>Tab</kbd> or <kbd>Enter</kbd> once the completion popup is open to accept the selected item - The menu does not close automatically when moving the cursor - When you delete text, previously correct suggestions are shown again - If you delete all text until the opening char (`@` or `:`) after applying a suggestion, the popup reappears again - Menu UI has been improved <img width="278" alt="Screenshot 2023-04-07 at 19 43 42" src="https://user-images.githubusercontent.com/115237/230653601-d6517b9f-0988-445e-aa57-5ebfaf5039f3.png">
