华为手机升级完补丁包后，uni.canvasToTempFilePath走fail，不走success

示例代码：

    <view>  
        <canvas canvas-id="myCanvas"></canvas>  
        <image :src="path" mode=""></image>  
        <button type="default" @click="open">拍照</button>  
    </view>  
</template>  
<script>  
export default {  
    data() {  
        return {  
            path: ''  
        };  
    },  
    methods: {  
        open() {  
            var ctx = uni.createCanvasContext('myCanvas', this);  
            var temp = this;  
            uni.chooseImage({  
                sourceType: ['camera'],  
                success(res) {  
                    uni.getImageInfo({  
                        src: res.tempFilePaths[0],  
                        success(s) {  
                            ctx.drawImage(res.tempFilePaths[0], 0, 0, s.width, s.height, 0, 0, uni.upx2px(750), uni.upx2px((750 * s.height) / s.width));  
                            ctx.save();  
                            ctx.setFontSize(14);  
                            ctx.setTextBaseline('bottom');  
                            ctx.setFillStyle('White');  
                            ctx.fillText('1233', 10, 20);  
                            ctx.draw(false, function(d) {  
                                uni.canvasToTempFilePath(  
                                    {  
                                        canvasId: 'myCanvas',  
                                        quality: 1,  
                                        success(ss) {  
                                            console.log(JSON.stringify(ss));  
                                        },  
                                        fail(f) {  
                                            console.log(JSON.stringify(f));  
                                        }  
                                    },  
                                    temp  
                                );  
                            });  
                        }  
                    });  
                },  
                fail(f) {  
                    console.log(f);  
                }  
            });  
        }  
    }  
};  
</script>  

<style></style>  

操作步骤：

华为 HONOR 20 Liite LAR-AL00在没有升级成2020年10月1日的那个安全补丁包之前没有问题，升级完后 uni.canvasToTempFilePath走fail不走success，错误
{"errMsg":"canvasToTempFilePath:fail SecurityError: Failed to execute 'toDataURL' on 'HTMLCanvasElement': Tainted canvases may not be exported."}

预期结果：

应该是走success能拿到图片地址

实际结果：

走的fail，{"errMsg":"canvasToTempFilePath:fail SecurityError: Failed to execute 'toDataURL' on 'HTMLCanvasElement': Tainted canvases may not be exported."}
