* Web: leave Ctrl+Tab and Ctrl+Shift+Tab to the browser (#5227)
eframe cancels the default action of every Tab keydown on its canvas
(egui moves focus with Tab), so browsers that let a page cancel their
shortcuts, such as Vivaldi, could not switch tabs while SolidCraft had
the keyboard. A capture listener on the window now stops Ctrl+Tab and
Ctrl+Shift+Tab before they reach the canvas, without cancelling them,
so the browser acts on them as usual. Plain Tab and Shift+Tab still
move between the app's fields. Desktop builds are unchanged.
web-api-test checks it in headless Chrome: Ctrl+Tab and Ctrl+Shift+Tab
keydowns are not cancelled, Tab still is.
