Density Video Textures for Particle Emission in 2.8?

Hi! Approx. a month ago I tried to simulate and render a project that involves density videotextures for particle emission in Cycles Blender 2.8beta. In 2.79 it worked, even though for the Keyed particle systems I had to reload the textures every time before rendering. In 2.8beta the density video textures did not seem to work at all. Is this a known problem? Or maybe I`m doing something wrong?
