Autocomplete detail tooltip opens at the wrong screen position

In Studio's code editor, the autocomplete detail tooltip — the signature/description shown for the highlighted suggestion — opens in the wrong place. Instead of appearing immediately to the right of the suggestion list, it is anchored to the right edge of the Studio window and is clamped against the right edge of the screen when the window is maximised, far away from the list. The suggestion list itself opens in the correct position.

This affects Studio 26.9.1 and 26.9.2. Expected behaviour: the detail tooltip sits directly beside the completion list, vertically aligned with the highlighted suggestion, as in releases before 26.9.1.
