Can you explain the differences between the SPFx and the WebPack Development tools (Unfortunately you ran out of time on the demo on todays monthly call) and what I can do without the SPFx tools ?
(I had the same issue as you did and the only way to fix it was to switch off MDS and then it worked well.)
eg can I use the cascading dropdowns without the SPFx framework ?
PS why no SPFx Label available ?
