problem with generated text in oneOf buttons

Describe the bug
Tested on fd8917e5.

I get the following "One of" buttons with three oneOf:

The behavior of the buttons is as expected, but not the labels on the buttons.

I expected that the first oneOf's buttons would be obj1-A and obj1-B,
the second obj2-A and obj2-B, and the third obj3-A and obj3-B.

Like this:

(this is w/ a single oneOf instead of allOf)

Here's the full spec:

The issue provides a complete OpenAPI 3.0.3 reproduction; start by loading it in Redoc and tracing the generated oneOf button labels across the three allOf entries. Done means each pair is labeled obj1-A/obj1-B, obj2-A/obj2-B, and obj3-A/obj3-B while button behavior remains unchanged.
