nvue 中的 bindingx 只要含有 rgba 则不生效

[jinmarcus]

代码如下：

<template>
    <view style="flex:1">
        <list ref="list" style="background-color:#f3f3f3;">
            <cell v-for="item in lists" :key="item.id">
                <text>{{item.text}}</text>
            </cell>
        </list>
        <view ref="header" style="position: absolute;top:0;left:0;right:0;height:100px;background-color: rgba(0,0,0,0.5);justify-content: center;align-items: center;">
            <text ref="text" style="color: rgba(255,255,255,1);">header</text>
        </view>
    </view>
</template>

<script>
const bindingX = uni.requireNativePlugin('bindingx')

export default {
    data() {
        const lists = []
        for (let i = 0; i < 100; i++) {
            lists.push({
                id: i,
                text: i,
            })
        }
        return {
            lists,
        }
    },
    mounted() {
        setTimeout(()=>{
            bindingX.bind({
                anchor: this.$refs.list.ref,
                eventType: 'scroll',
                props: [
                    {
                        element: this.$refs.header.ref,
                        property: 'background-color',
                        expression: `rgba(0,0,0,y<20?0.5:0.5-(((y-20)/200>0.5?0.5:(y-20)/200)))`,
                    },
                    {
                        element: this.$refs.text.ref,
                        property: 'color',
                        expression: `rgba(y<120?255:51,y<120?255:51,y<120?255:51,y<20?1:(y<120?(1-(((y-20)/100>1?1:(y-20)/100))):(y>220?1:(y-120)/100)))`
                    },
                ],
            })
        }, 500)
    },
}
</script>

HBuilderX 3.5.3.20220729 版本中，以上代码运行后，只要expression含有rgba，则无效，视频如下： https://vkceyugu.cdn.bspapp.com/VKCEYUGU-2990ed4f-051f-4f15-9beb-2cc68d0c4a77/0741aa05-b70d-4072-9a6f-f0a2f66349dd.mp4

但是在HBuilderX 3.4.7.20220422 版本中，则运行正常，视频如下： https://vkceyugu.cdn.bspapp.com/VKCEYUGU-2990ed4f-051f-4f15-9beb-2cc68d0c4a77/b69c160c-ef2e-4fb3-995f-2ee2b276771c.mp4

请问是什么问题导致？
