Percent effect starts by zero at every value change #4934

What happened?

Since last update the percent effect starts at zero instead of the last value.
i use this effect with two presets to light my stairs.

in the previous firmware it moved from 100 to 0 percent backwards. now it turns immediately to zero.

My presets below.

To Reproduce Bug

Preset 1 (Turns the lights on):
{"on":true,"bri":47,"transition":1,"mainseg":0,"seg":[{"id":0,"start":0,"stop":307,"grp":1,"spc":0,"of":0,"on":true,"frz":false,"bri":255,"cct":127,"set":0,"col":[[117,71,36,0],[0,0,0,0],[0,0,0,0]],"fx":98,"sx":15,"ix":100,"pal":0,"c1":128,"c2":128,"c3":16,"sel":true,"rev":false,"mi":false,"o1":false,"o2":false,"o3":false,"si":0,"m12":0},{"id":1,"start":307,"stop":726,"grp":1,"spc":0,"of":0,"on":true,"frz":false,"bri":255,"cct":127,"set":0,"col":[[117,71,36,0],[0,0,0,0],[0,0,0,0]],"fx":98,"sx":18,"ix":100,"pal":0,"c1":128,"c2":128,"c3":16,"sel":true,"rev":true,"mi":false,"o1":false,"o2":false,"o3":false,"si":0,"m12":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0}]}

Preset 2 (turns the leds off):
{"on":true,"bri":47,"transition":7,"mainseg":0,"seg":[{"id":0,"start":0,"stop":307,"grp":1,"spc":0,"of":0,"on":true,"frz":false,"bri":255,"cct":127,"set":0,"col":[[117,71,36,0],[0,0,0,0],[0,0,0,0]],"fx":98,"sx":15,"ix":0,"pal":0,"c1":128,"c2":128,"c3":16,"sel":true,"rev":false,"mi":false,"o1":false,"o2":false,"o3":false,"si":0,"m12":0},{"id":1,"start":307,"stop":726,"grp":1,"spc":0,"of":0,"on":true,"frz":false,"bri":255,"cct":127,"set":0,"col":[[117,71,36,0],[0,0,0,0],[0,0,0,0]],"fx":98,"sx":18,"ix":0,"pal":0,"c1":128,"c2":128,"c3":16,"sel":true,"rev":true,"mi":false,"o1":false,"o2":false,"o3":false,"si":0,"m12":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0}]}

Expected Behavior

effect (preset 2 as given) should move backwards from 100 to zero instead of turning all leds off.
