No whitespace after bolded and italicized words in HTML

[QuantumNeon]

Issue description

As per title, the whitespaces between bolded and italicized words disappear in the exported HTML file, while they work as intended in the preview. I resorted to enclosing the words in HTML bold tags but it kinda defeats the purpose (while still being effective).

I opened the same txt file in other markdown apps (ATOM, MarkdownPad2) and their output is correct.

Markdown to reproduce

**Word.** *word*  
or  
**Word.** _word_
