Vaadin-grid doesn't work with Vaadin 10.0.0.alpha9 and fails with `grid._createPropertyObserver is not a function`

Description

Vaadin-grid doesn't work with Vaadin 10.0.0.alpha9 and fails with grid._createPropertyObserver is not a function. By including the com.vaadin:vaadin:10.0.0.alpha9 dep into the project the com.vaadin:vaadin-grid-flow:1.0.0.alpha3 is added on the classpath; by adding bower dependency of "vaadin-core": "v10.0.0-alpha9" the "_target": "4.1.0-alpha1" grid element is added to bower_components (yup I'm not using webjars nor vaadin bom).

Expected outcome

Grid should just work. It works with vaadin:10.0.0.alpha8.

Actual outcome

Grid fails with grid._createPropertyObserver is not a function in the JavaScript console.

Tried to upgrade vaadin-grid element to 4.1.0-alpha2, the issue persists.

Please report in the correct repository (Flow). Vaadin-grid works fine by itself so there's something wrong in the integration.

Heh, the correct repository is actually vaadin-grid-flow, not the Flow repo directly.
