Bug in grid-dense-theme Recipe

[khauser]

With the grid-dense-theme I'm able to compact a grid. But sometimes on different grids the first data line is higher than the others. Also the sample from the recipe has this problem. I have tested this with firefox and chrome.

I played a little bit round and it seems to work with:

:host([theme~="dense"]) [part~="cell"] {
  min-height: var(--lumo-size-xxs);
}
:host([theme~="dense"]) {
  font-size: var(--lumo-font-size-xs);
}
:host([theme~="dense"]) [part~="cell"] ::slotted(vaadin-grid-cell-content) {
  padding: 1px var(--lumo-space-s);
}

:host([theme~="dense"]) [part~="first-row"] [part~="cell"]:not([part~="details-cell"]) {
  border-top: 0;
  min-height: var(--lumo-size-xxs);
}

So first-row does have it's own min-height declaration.
