It seems to have too many glitches or edge-cases when working with other HTML widgets. After years of experience perhaps one learns to work around such, but it seems overly complicated for smaller-shop apps. "Enterprise" can afford to hire a dedicated CSS expert, mom-and-pop can't. We need KISS GUI's, not 4D-chess layout rocket science. With minor tweaks for screen-size adjusting, I believe WYSIWYG GUI makers that actually work right can come back in style.
