New Input Beta - Prerelease Trade Window unable to complete offers

In the new input beta, with the prerelease trade UI overlay enabled, I am unable to make an offer and complete the trade. Clicking the button in the UI doesn’t work, and neither does pressing ‘o'. Trades work properly when disabling the prerelease UI overlay and pressing ‘o’ to complete the trade. I saw this with Tam and Argyve in Joppa, but didn’t test elsewhere.
