Suggestion issue for Variable Arity Parameters #4267
Description
Example code:
class Test {
static Foo foo = new Foo();
static Foo bar = new Foo();
void test(Foo... foo) {
}
void test2() {
test(|); // cursor at "|"
}
}
When the cursor is in the "test()", and trigger suggestions using shortcut, "foo" and "bar" will appear in a dropdown list for selection, there is no problem. After choosing one,the code is:
test(foo,|) ; // cursor at "|"
Now when I try to trigger suggestion, "foo" and "bar" not appear.

Completion after a comma and space shows all suggestions(including incorrect suggestions). Only the first completion is correct. I'm using VScode.
