• 当前 Bug 的表现（可附上截图）

• 预期表现

canvas.style.width = canvas.width(未横屏之前的宽)

canvas.style.height = canvas.height(未横屏之前的高)

• 复现路径

• 提供一个最简复现 Demo

测试环境ios微信小游戏

以下为game.js代码片段

let sysInfo = wx.getSystemInfoSync();

let canvas = window.canvas;

let orgWidth = canvas.width;

let orgHeight = canvas.height;

console.log(“org canvas:”, canvas);

canvas.style[“transformOrigin”] = “0% 0% 0px”;

canvas.width = sysInfo.pixelRatio * orgHeight;//宽高翻转

canvas.height = sysInfo.pixelRatio * orgWidth;//宽高翻转

canvas.style.bottom = “0”;

canvas.style.right = “0”;

canvas.style.top = “0px”;

canvas.style.left = “0px”;

canvas.style[“transform”] = “matrix(” + (1 / sysInfo.pixelRatio) + ", 0, 0, " + (1 / sysInfo.pixelRatio) + “, 0, 0)”;

console.log(“update canvas:”, canvas);

这里打印出来canvas.style的width，height一直都是0，我想知道是什么原因？，参见下图

//egret.wxgame.WebPlayer中也是这样设置，最后看到canvas.style 宽高有值（原canvas的宽高）
