Trailing space makes bold line apply to next lines

applies to next contiguous sequence of non empty lines (chars, numbers, symbols)

example input:

**a **
b
c

d

This is a quirk of Live Preview. If you switch to Reading View you’ll see a more correct rendering.

But strictly speaking, the example shouldn’t render as bold at all.

so it’s a bug

the spec is a dummy tho cos the text will be flickering from styled to unstyled while typing

That’s not the spec’s concern. “Live preview” style editors are a relatively recent thing in Markdown’s history.

my man don’t sidetrack the conversation with theory, it shouldn’t apply bold to next lines

I’m not “sidetracking” with “theory”. The spec is a practical reference. Please be civil — dismissiveness isn’t how we roll here.
