Configuring brush chart with multiple targets throws exception

[Zapo93]

I am creating a POC for a project that requires multiple grouped charts with a brush chart that controls all.
I am using the angular wrapper, but it does not allow adding the targets property in the latest version published in NPM. This is why I configured the brush charts with the targets property, using the JS ApexCharts constructor. However with this configuration an exception that .forEach is not defined is thrown here (src/modules/Core.js:619)
targets.forEach((target) => {

After some debugging it turned out that when targets is an array, targets gets evaluated as a boolean "true" here (src/modules/Core.js:615):
let targets = Array.isArray(w.config.chart.brush.targets) || [w.config.chart.brush.target,]

After changing the code in the browser with the following everything works as expected:
var a = i.config.chart.brush.targets || [i.config.chart.brush.target];

Currently I am using a workaround I found in a different issue, because I`m not sure if this is actually a bug or the problem is in my configuration:

chart: {
        brush:{
          targets:['main-chart','sec-chart'],
          enabled: true
        },
        id: 'brush-chart',
       ....
}
