Changed result matching comment in JS class member in ^0.45.0 #2867

^{Originally posted by donmccurdy August 3, 2026}
I'm trying to match any JSDoc comment on a JavaScript class member containing the JSDoc tag @memberof, and to remove that tag. In v0.44 I used the following successfully:

id: no-jsdoc-memberof
message: >
  ES6 class members do not require @memberof tags.
severity: error
language: JavaScript
files:
  - packages/engine/Source/**/*.js
rule:
  kind: comment
  regex: "(?i)@memberof"
  pattern: $COMMENT
  inside:
    kind: class_declaration
    stopBy: end
transform:
  COMMENT_FIX: replace($COMMENT, replace="(?i)\n.*@memberof.*\n", by="\n")
fix: '$COMMENT_FIX'

As of v0.45, the rule no longer detects any issues on the following code block:

class MyClass {
  /** @memberof MyClass.prototype */
  get myProp() { return 1; }
}

If I remove the pattern: $COMMENT line, the rule detects the issue again, but the transform no longer applies. I'm not 100% sure that I've understood some relevant FAQ entries so I'm not reporting this as a bug yet, but it seems unexpected to me to get a different result from v0.44 and v0.45. Any advice appreciated, thanks!

If this is intended, I can remove the transform. Just using ast-grep to detect the issue would be OK for my purposes, without necessary auto-fixing it.
