Trailing spaces causes initial characters to be swallowed

[delucis]

If the content string passed to <Markdown> ends in one or more spaces, the equivalent number of characters are removed from the start of the content.

Some examples:

	Input	Output
✅	<mark>Highlighted word</mark> with no trailing space	<mark>Highlighted word</mark> with no trailing space
❌	<mark>Highlighted word</mark> with trailing space	mark>Highlighted word</mark> with trailing space
❌	Non-initial <mark>Highlighted word</mark> with trailing spaces	-initial <mark>Highlighted word</mark> with trailing spaces

Minimal reproduction: https://stackblitz.com/edit/github-futqf6?file=src%2Fpages%2Findex.astro

I wasn’t able to reproduce this in the marked playground, so I’m guessing it’s something specific happening here or perhaps in the plugins astro-remote uses?

Darn... I thought we had this issue fixed... its something with the dedent function that seems to be causing it... I guess we only partially fixed it in #23 😢
