When the full-screen range picker adds months above the ones on screen, extendMonths() puts the scroll back by however much the list grew. An engine with scroll anchoring moved it back as well, so a reader paging up landed half a year on, and a press meant for one day chose another. The calendar now opts out of scroll anchoring (`overflow-anchor: none`) and the picker's own correction is the only one, in every engine alike. A test holds what sits under a fixed point of the list while it grows. The browser plugin retries an action the way it retries an assertion: when the page takes longer than a second to handle a press, it presses again. On a loaded runner the full-screen picker, which re-renders every day of every month it holds, took that long — so its toggle was pressed a second time under the picker it had just opened, and never landed, and a day pressed twice became the range's end as well as its start. `pressOnce()` sends a press that must not be repeated exactly once, with Playwright's own wait for the element; the picker's toggle, its paging keys, its days and its Save go through it, and so do the menu triggers that toggle. Browser 300 passed on Chrome, Firefox and WebKit on macOS, and the date picker and menu tests 61 passed on Linux Firefox and WebKitGTK held to two busy cores. Feature 1159 passed.
