Missing inspect button in dev tools

[dragomirweb]

tested on versions 7.6.0+ while using the host app: http://localhost:3000/__devtools__/ in the components the inspect button is missing, using the inspect kb shortcut opens the floating inspector even when it;s turned off.
tried clearing cache, ram dns browser ... even my life but still the button is gone might be to the recent changes to the inspect shortcut. Mentioning that in the floating dev tools the inspect button is still near the search bar.

This is by design. Because it doesn't work in separate window mode. See #540.
