Doc of paragraph in markdown violates a rule of fill() #15877
Description
Prettier 3.1.1
Playground link
--parser markdown
--tab-width 4
--prose-wrap alwaysInput:
a a
b b
c c
Doc:
[
fill([
"a",
line,
"a ",
markAsRoot(literalline),
line,
"b",
line,
"b ",
markAsRoot(literalline),
line,
"c",
line,
"c",
]),
hardline,
]
Expected behavior:
The result doc should preserve the following invaliant:
prettier/src/document/printer.js
Lines 442 to 443 in bab8922
I haven't found user-facing problem yet. I found it investigating #15836 (comment).
