Research direction

Investigate the inline toolbar component to understand how the convertTo button visibility is controlled. Look at the configuration merging logic to ensure that when `inlineToolbar` is explicitly set, the convertTo should respect that configuration. Check if there is a missing check for the availability of convertors. The relevant files are likely in `src/components/inline toolbar.ts` and `src/components/tools.ts`.
