How to Disable auto id attributes in Heading tag?

I don’t know why but WP is automatically adding id attributes to h2 tags. I am not supplying any id or class attribute and I don’t need it. Also, it’s adding type=1 to ol tag that’s not needed in my case.

You can see it on this page: https://idioms.a2hosted.com/2022/02/15/its-not-brain-surgery/

Please help, how to stop it?

I need this:

h2Meaning/h2

h2Example Sentences/h2

h2Origin/h2

This is what WP doing with it.

h2 id=meaningMeaning/h2

h2 id=example-sentencesExample Sentences/h2

h2 id=originOrigin/h2
