[ML] Fix single metric viewer chart resize. (#57578)

Fix to trigger a chart update with the correct width when resizing the browser window. Previously after a browser refresh, or opening the view from a bookmarked URL, the chart would not resize until a state change was made to the view (such as moving the zoom slider or altering the time range).
