Upon inserting link, new line will be created, however GitHub parse it and made it a space, could you confirm that you manually removed the newline that is inserted upon clicking insert from the dialog?

No newline was added, but excess space, but after dot, not before.

@k0shk0sh It's a very annoying bug, so please prioritize it if possible. I'd say that markdown rendering is a vital part of this application, as you should trust what you see to don't have a need to use a browser for that..
Markdown preview does not handle newline cases correctly.
For example,

When you click preview it actually shows,

The actual result is,

The newline between "correctly." and "For example" is not shown in preview, but it appears when processed. In general newline has some problems when in preview mode.
