why not combine these predicates?

| if (node.jsDoc) { | ||
| const typecasts = flatten<JSDocTag>(map(node.jsDoc, doc => filter(doc.tags, tag => tag.kind === SyntaxKind.JSDocTypeTag))); |

this.p = 42;should also work. I just want to confirm that this is not addressed in this PR.

Based on #17176, since that changes some of the machinery that could have affected this.
