Description

Steps to reproduce:

  1. Open Activity Monitor or Task Manager and note the resting CPU usage of the Code Helper process
  2. Paste this into vscode:
<div>
    <span>This is just a test</span>
</div>
  1. Double click the opening span tag
  2. Type a to rename to an anchor tag
  3. Watch the CPU usage of the Code Helper process rise to +90% and stay there.

Note: At this point, auto rename no longer works.

Contributor guide

Research direction
Investigate the event handler for tag renaming and trace CPU usage spikes. Look for infinite loops or inefficient DOM traversal in the rename logic.
