Coral UI: Request a new schema version button doesn't work

# What happened?

When I try to modify an existing schema for a given topic in the Coral UI (e.g. `/coral/topic/delete-me/schema`) and click on the button labeled "Request a new version", I'm not redirected to the expected page with the request form.

The link of the button looks good to me (e.g. `/coral/topic/delete-me/request-schema?env=DEV_SCH&schemaType=AVRO`) and the link works when I open it in a new browser tab. However, when I open it in the same tab, I can briefly see the expected page, but I'm getting routed back to the topic details (e.g. `/coral/topic/delete-me/schema`).

# What did you expect to happen?

When I click on the "Request a new version" button, I'm getting redirected to the form for schema update requests.

# What else do we need to know?

It only affects the new Coral UI. I can't see any errors in the web console or network console.

Requesting schema updates from the top ("Request a new" dropdown) still works as expected.

Also requesting the first version (e.g. for a new topic) still works. I only had this issue while updating schemas.
