@mlippautz -- Could you please look into the issue, kindly re-assign if this is not related to your changes.

Assigning based on file names is almost certainly not going to yield any good candidates for owners.

The CL in question is completely unrelated. 

Thank you for the update.

Nothing in my change which should increase stack usage. Stack overflow attaching a very deep dom tree.
