When nested folding ranges end on the same line, the outer range is incorrectly truncated #5750
Description
Describe the bug
Switch case folding doesn't fold until the next case if a function has parameters that span multiple lines (I think that is the issue, but maybe something similar at least?).
To Reproduce
Add a file with this sample:
Future<void> f() async {
switch (1) {
case 1:
print('something');
someBigFunctionName(
someReallyReallyLongNameHereSoItHasToSplit: 1234567,
);
case 2:
print('another thing');
print('yet another thing');
case 3:
print('more things');
}
}
void someBigFunctionName({
int? someReallyReallyLongNameHereSoItHasToSplit,
}) {}Try to fold at case 1 and see that it doesn't fold someBigFunctionName.
Expected behavior
It folds someBigFunctionName.
