Material Bars - SVG Defs is not filled properly

[Eduardo Mioto]

Hello everyone, i'm facing a strange problem related with <svg>rendering on Material Bars.
During the first time that the page is accessed, the chart is always rendered properly, without any questionable behavior.
If some parameter is changed on the screen, and the chart is asynchronously rendered again, the tags <defs> on  <svg> is not properly filled.
Follow below the content of  two behaviors faced;
