What steps will reproduce the bug?
Because of an incorrect early return here, when a mocked setInterval is triggered, processing of timers stops, even if there are more timers queued, that are already due.
Pull request incoming.
`test.skip("setInterval stops processing of timers", async (t) => {
t.mock.timers.enable({ apis: ["setInterval", "setTimeout"] });
const f1 = t.mock.fn();
const f2 = t.mock.fn();
setInterval(f1, 1000);
setTimeout(f2, 1001);
assert.strictEqual(f1.mock.callCount(), 0);
assert.strictEqual(f2.mock.callCount(), 0);
t.mock.timers.tick(1001);
assert.strictEqual(f1.mock.callCount(), 1);
assert.strictEqual(f2.mock.callCount(), 1);
});fails with:
