Grid PartNameGenerator sample has unnecessary classname about docs HOT 3 OPEN

The styling example is actually correct. You missed that the Grid in the sample has the classname styling applied to it, and also used in the css selectors.

However, this is an unnecessary complication of the sample, and should be addressed (by removing the .styling classname from the selectors).

There is also a workaround in the sample for an issue in the way part names are applied, which should be fixed in the Grid component itself: vaadin/web-components#7447

from docs.

Using "styling" as a class name for a grid was not exactly intuitive :-)

from docs.

Keeping this open so we remember to remove the classname selector from the sample (and remove the classname entirely when vaadin/web-components#7447 has been fixed).
