I find this happens especially often when I’m editing on a touch screen device.
In most text editors (e.g. Google Docs, Bear…), if your selection includes a trailing space, that doesn’t mean you end up bolding the entire selection AND all the text that follows. So I think the current behavior will seem like a bug to most people.
Edit: Well, it doesn’t seem like a bug to Whitenoise, so I’m posting as a feature request, per their request.
Bumping this one. I still think this should be thought of as a bug. This non-standard behaviour causes minor friction for me (and presumably most users?) many times per day.
Whenever I select text, I’m careful to pick up or avoid adjoining whitespace because it will be transmitted to any program I paste to.
Bolding is slightly different. Many editor formats bold only text and not the whitespace. But with markdown there has to be a decision about where the markup syntax is placed, and I can understand that respecting any whitespace included.
