💻 Code

class A {
    /** 
     * Description text here.
     * 
     * @virtual
     * */
    foo() { }
}

class B extends A {
    override foo() { }
}

class C extends B {
    override foo() { }
}

🙁 Actual behavior

Only the description text is provided for C.foo.

🙂 Expected behavior

Both the description text and the tag should be provided for C.foo, just as the behavior of B.foo.

Additional information about the issue

I'm trying to provide a solution for #1534 by using typescript-eslint + JSDoc tag. This bug makes @virtual tag disappear and I will not be able to override C.foo in "strict-virtual" mode.

Also note that @inheritdoc tag doesn't work here. Adding @inheritdoc to B.foo will only provide @inheritdoc itself to C.foo, instead of the @virtual tag, which is an unexpected and unuseful behavior.
