REPRODUCTION
I was able to reproduce the failure with the following on iPad Simulator running iOS26.2 ToT with the following:

run-webkit-tests --ios-simulator --force --child-processes=1 --no-retry --exit-after-n-failures=5 --iterations 100 imported/w3c/web-platform-tests/html/semantics/forms/the-select-element/customizable-select/select-keyboard-behavior.optional.html

I am going to mark expectations as a pass fail while this pends investigation.
