style: fix comment bubble appearance upon zoom When browser zoom is used, the font size increases. As a result, the text balloon icon used in the comment bubble increases as well. However, the rectangle in which the icon resides is kept the same size, causing the result to look bad. Use 'em' units, which are relative to the font size, rather than pixels, for all relevant style properties of the bubble, including size, padding and border-radius. With these settings, the bubble always looks well, regardless of zoom value.
