When merging to cells that contain only markdown, I expected the result to be one block of markdown in the same tagged template literal, so:
cell 1: md
Here is some prose.
cell 2 md
Here is some more prose.
combined cell: md
Here is some prose. Here is some more prose.
Instead, the merged cells contains: md
Here is some prose.md
Here is some more prose. and throws a “SyntaxError: Unexpected token”.
Also, if one of the cells to be merged hasn’t run yet, then that cell disappears after merging.
