Muliple NBSPs in code secontion in markdown string are collapsed

Prettier 2.7.1 Playground link

--parser markdown

Input:

For example, the string `"a   b"` (three spaces between _a_ and _b_) separates _a_ and _b_ more than `"a b"` (one space between _a_ and _b_).

Output:

For example, the string `"a b"` (three spaces between _a_ and _b_) separates _a_ and _b_ more than `"a b"` (one space between _a_ and _b_).

Expected behavior: I replaced regular spaces with Non-breaking spaces to prevent the collapsing of the spaces that occurs with regular spaces, but if you look at "a   b" it shouldn’t be collapsed as it renders correctly.

original the doc had 3 regular spaces “a b” that does collapse down

It’s collapsed by the browser. In the HTML markup, it’s still 3 spaces. I’d vote for removing this replace unless there really is a case when it’s doing the right thing.

Actually, according to the CommonMark spec, the only correct replacement would be to replace line endings with spaces.
