## Issue
4797: Markdown preview breaks when using a lbry link in angle brackets
This is similar to the Embed case in commit dbcd677e.
## Change
Replaced it with a dummy link that looks like what the final outcome would be, but would not be clickable.
Again, similar to the embed case, unless there is a way to pass the store over, I don't have an alternative that makes sense: Adding a dummy router or replacing it as a regular <a> will just make React spew security errors.
Not being able to click it is not ideal as we (as a user) can't verify our links, but it's better than the current case of not rendering anything at all.
## Issue
4644: Markdown Preview breaks when <iframe> is present
Error: "Invariant violation: could not find 'store' ..."
## Change
Until we figure out a way to pass the store to the SimpleMDE preview formatter, just replace the embed with a stub region.
Technically, the other modes can have a quick-action button as well, but for now it's not implemented since it's unlikely to be used.
The first usage will be to house the "toggle markdown editor" button, but it can be used for anything. The caller will handle the action.
It will be located at the upper-right, which is a better place for such a button. Putting the "toggle markdown editor" button on the bottom seems too far away and seems to make the 'Done|Cancel' area too busy/cluttered.
