Steps to reproduce

SlotTag Component:

html:

script: const slotDefault = !!useSlots().default; console.log("default exists: " + slotDefault);

App.vue:
html:

browser console output:
default exists: (...args) => {
// If a user calls a compiled slot inside a template expression (#1745), it
// can mess up block tracking, so by default we disable block tracking and
// force bail out whe…

What is expected?

the code for the annotation should not be detected, expecting a undefined value to be returned
Expect the output to be log below:
default exists: false

What is actually happening?

Any additional comments?

Start with the linked SFC minimal reproduction and inspect how useSlots().default is produced for the commented-out slot content. Trace the slot behavior in the Vue core implementation and verify that the reproduction logs false rather than a slot function when the annotation is commented out.
