Steps to reproduce:

run Sandbox under ShadowDOM polyfill
drag Menu and Toolbar onto the cavas
run Preview
in the Preview window, click the "+" button to open the dropdown-menu. You would notice the dropdown-menu is positioned incorrectly.

This is because under polyfill, styles leak downwards.

The workaround is to change g-menu's id to a different value (e.g. menu123)
