`preferSingleLine` sometimes doesn't collapse arguments, until a comment is added
Describe the bug
dprint-plugin-typescript version: 0.79.0
The following has two sets of input code that are identical except for the addition of a comment above <Component
in the second one. (Note that the comment can be completely blank, the length doesn't matter).
However, the second one is (correctly) collapsed, while the first one isn't. I would expect both to be formatted the same, except for the addition of the comment. This only happens when preferSingleLine
is enabled, and I'd expect it to be collapsed like the second one.
Input Code
Array.from(
{ length: 1 },
(_, i) => (
<Component
prop1={somePropFooBlah}
prop2={`Some string here askdjalskdjalskdjlaskjd`}
prop3={[1, 2, 3, 4]}
/>
),
);
Array.from(
{ length: 1 },
(_, i) => (
// hi
<Component
prop1={somePropFooBlah}
prop2={`Some string here askdjalskdjalskdjlaskjd`}
prop3={[1, 2, 3, 4]}
/>
),
);
Expected Output
Both same, but one with a comment.
Actual Output
Array.from(
{ length: 1 },
(_, i) => (
<Component
prop1={somePropFooBlah}
prop2={`Some string here askdjalskdjalskdjlaskjd`}
prop3={[1, 2, 3, 4]}
/>
),
);
Array.from({ length: 1 }, (_, i) => (
// hi
<Component
prop1={somePropFooBlah}
prop2={`Some string here askdjalskdjalskdjlaskjd`}
prop3={[1, 2, 3, 4]}
/>
));
