Fix flaky OIDC "verifiy dialog" test (#33188)

This test was flaking. The problem appears to have been that we were clicking
"Continue" twice in succession; the intention was that we click on two
*different* "Continue" buttons, but sometimes we ended up clicking in the same
one twice.

Fix it by waiting for the content to change after the first click.

Fixes: #31316
