Markdown line wraps parsing error.

[BHznJNs]

What’s broken?

When using editor.blocksToMarkdownLossy(editor.document) to export the editing content into markdown, the all line wraps will be converted into \n\n (two line breaks), but when using editor.tryParseMarkdownToBlocks to convert the converted markdown text back to blocks, the \n\n will be treated as a extra empty line.

For example,
for such a content:

foo
bar

exported markdown content:

foo\n\nbar

and after reimported:

foo

bar

and re-exported:

foo\n\n\n\nbar

There is an extra line appeared after export and import, even there is no modification applied.

What did you expect to happen?

When using editor.tryParseMarkdownToBlocks, treat the line breaks correctly.
For example,
for markdown content:

foo\n\nbar

it should be rendered as:

foo
bar
