JSDoc @this/@lends/@namespace tags are ignored inside Object

MyElement.d.ts

declare class MyElement {
    constructor(target: Element);
    target: Element
}

MyElement.js

@this on globally defined function works as expected, Ctrl+Space shows the correct type of target - Element!

@this before function in the object doesn't take into account!

@lends before the object itself is also not taken into account!

the same with @namespace

I couldn't find the way to point the correct "this" type for function in objects.

Reproduce the behavior with the MyElement.d.ts and MyElement.js snippets and compare the global function case with the functions and object-level tags. Verify the JSDoc handling behind VS Code completion, then confirm that @this, @lends, and @namespace are recognized inside objects and that Ctrl+Space reports the expected type.
