Vaadin Grid Row Hover Style

I’m using Vaadin grid 1.2.0 with Polymer. I see that the API already provides several custom styling mixins for cells, selected row cells, striped row cells, etc. However, we were wondering if there was a way to either change or disable the background color when hovering over a row in the table. Currently, vaadin-grid defines this styling on lines 306-308 of vaadin-grid.html:

tbody:not(.touch):not(.scrolling) .vaadin-grid-row:hover td { background-color: #eeeeee; } Is it currently possible to access/modify this from within a parent Polymer component? I’ve tried something like:

vaadin-grid:hover { --vadin-grid-selected-row-cell: { background-color: white; } } but it doesn’t have any effect.
