The "model selector can open, close, reopen, and close again" test still flaked
on loaded CI runners even after re-tapping the backdrop: the model-selector
sheet re-renders as its model list settles, and Gorhom drops backdrop presses
during that churn, so the tap never dismisses within the retry window.
Fall back to dragging the sheet handle down, which drives Gorhom's pan-to-close
directly and is unaffected by the backdrop churn (mirrors the resilient close in
e2e/helpers/app.ts). The backdrop tap remains the primary path, and the
post-close "stays hidden" guard that protects the dismiss-then-re-present
regression is unchanged. Verified locally by forcing the fallback (backdrop tap
disabled): the handle drag closes the sheet on its own.
