Select All doesn't work in the Web designer

In web projects, Edit → Select All does nothing while a Web page designer is the active view.

Steps: add several controls to a web page (for example, three checkboxes), then choose Edit → Select All from the menu bar. Expected: every control on the page becomes selected, exactly as in the desktop Window designer. Actual: nothing happens; the selection is left unchanged.

Select All still works in the Web designer through its other entry points — the keyboard shortcut typed while the designer canvas is focused, and the Select All item in the Structure pane's right-click menu — so the gap is specific to the menu bar command, which silently does nothing. This breaks parity with the desktop Window designer, where the same menu command selects all controls, and leaves users who reach for the menu (or the menu item's shortcut) unable to select every control on a web page before moving, deleting, or duplicating them.
