Validate the diagnostic

Confirm the reported code matches this rule before you edit it.

Confirm the reported code matches react-doctor/no-fixed-inside-transformed-ancestor. Compare it with the Before example and verify the same API, framework, and execution context. Treat it as a false positive only when one of those conditions differs.

Compare the code

The corrected pattern shows a focused way to address the diagnostic.

Reported pattern

<div className="scale-95"><div className="fixed inset-0">Dialog</div></div>

Corrected pattern

<>
  <div className="scale-95">Page</div>
  <div className="fixed inset-0">Dialog</div>
</>;

How to fix

Use the corrected pattern as a reference. Preserve behavior that the rule does not require you to change.

Copyable fix prompt

Copy this self-contained prompt into your coding agent after you confirm the diagnostic.

Fix every confirmed react-doctor/no-fixed-inside-transformed-ancestor diagnostic in the current repository. Required change: - Move viewport-fixed UI outside transformed ancestors, or intentionally use absolute positioning within that containing block.

Reference transformation:Before:

<div className="scale-95"><div className="fixed inset-0">Dialog</div></div>

After:

<>
  <div className="scale-95">Page</div>
  <div className="fixed inset-0">Dialog</div>
</>;

Constraints: - Confirm the reported code matches the Before pattern. - Make the smallest change that fixes the root cause. - Preserve behavior and interfaces unrelated to this diagnostic. - Reuse existing project components, utilities, and conventions. - Do not introduce render-phase side effects, render-phase state updates, or Hooks rule violations. - Use existing brand assets, product facts, content, and design tokens. - Do not invent claims, customer data, typefaces, or artwork. - Adapt identifiers and framework details instead of copying blindly. - Do not disable the rule or suppress matching code. Verification: - Run focused tests for the changed behavior. - Run React Doctor and confirm this diagnostic no longer appears. - Report the files changed and any checks you could not run.
