STR: - Open http://labs.jensimmons.com/examples/grid-content-1.html - open the inspector - find and select the <main> element - in the rule-view, click on the grid icon next to display:grid; - click on the "repeat(5, 16vw)" value - change this value to something else, like "repeat(5, 17vw)" - click on another value, like the one just below it "repeat(12, 16vw)" => The grid highlighter is hidden. It should remain visible. This is most probably because the whole rule is refreshed and we loose some piece of state in the meantime. This is related to bug 1302536. Not sure if it should block it, but it seriously impacts the usefulness of this feature.

In fact, in the last step of the STR in the previous comment, you do not need to click inside another value. Just blurring the first value will do it. Gabriel: can you think of a way to fix this?
