Reducer doesn't work for account icon on globo

[jrmuizel]

When trying to reduce the purple J account icon from https://bug1878024.bmoattachments.org/attachment.cgi?id=9433451
Test case reducer gives:

This is a reduced version of the above that shows a similar problem. https://bug1878024.bmoattachments.org/attachment.cgi?id=9433477

Though I get:

No result received. Try running `reduceTestCase($0)` in the console.
