if with long test, long body and prettier-ignore in else statemet splits test line early

Prettier 2.0.5
Playground link

--parser babel

Input:

if (A_TEST_OF_A_CERTAIN_LENGTH) {
  A_CODE_OF_A_SUFFICIENT_LENGTH_______________;
} else
  // prettier-ignore
  some_call();

Output:

if (
  A_TEST_OF_A_CERTAIN_LENGTH
) {
  A_CODE_OF_A_SUFFICIENT_LENGTH_______________;
}
// prettier-ignore
else some_call();

Expected behavior:

if (A_TEST_OF_A_CERTAIN_LENGTH) {
  A_CODE_OF_A_SUFFICIENT_LENGTH_______________;
}
// prettier-ignore
else some_call();

Notes:

• The bad behavior somehow involves both the length of the test, and the width of the body of the if.

Start with the supplied JSX reproduction in the Prettier Playground using the Babel parser, then trace how the formatter handles the long if condition, body, and prettier-ignore before else. Done means the input retains the condition on one line and matches the expected output without the early split.
