B4J Question [ABMaterial] graphics with 4.30 doesnt work on Firefox/IE?

[MbedAndroid]

question about this 4.30 update (and also 4.25)
i'm using ABMcanvasObject for drawing graphics see code below.
This works on Chrome with 4.30/4.25 but not Firefox/IE anymore
What could cause this?

(4.05 works out of box with this code)
NB pages are much faster loaded with 4.30!

Sub BuildRainbucket(rain As Double,width As Int,height As Int,id As String) As ABMCanvasObject
   Dim bucket As  ABMCanvasObject
   Dim const stb=height-30 As Int
   Dim const stt=30 As Int
   Dim const tg=0.27 As Double 'precaluculated 15 deg tan

   Dim level=rain*40 As Int
   Dim y=Sqrt(1/tg*4000) As Double 'x1 displacement
   Dim x=y*tg/2 As Double
   Dim x2=width/8 As Int
   Dim top=y As Int
   If rain>200 Then rain=200 ''limit amount of rain just to prevent skyhigh filled bucket
   bucket.beginPath
   bucket.moveTo(width/2-x2,stb)
   bucket.lineTo(width/2-x-x2,stb-y)
   bucket.lineTo(width/2+x+x2,stb-y)
   bucket.lineTo(width/2+x2,stb)
   bucket.lineTo(width/2-x2,stb)
   bucket.fillStyleColor("#d3d3d3")
   bucket.fill

   y=Sqrt(1/tg*level)
   x=y*tg/2
   bucket.beginPath
   bucket.moveTo(width/2-x2,stb)
   bucket.lineTo(width/2-x-x2,stb-y)
   bucket.lineTo(width/2+x+x2,stb-y)
   bucket.lineTo(width/2+x2,stb)
   bucket.lineTo(width/2-x2,stb)
   bucket.fillStyleColor("#0000ff")
   bucket.fill

i didnt copy the www folder items from the template example, just used the same www as for 4.05. Then this issue is gone
