请问wx.loadFontFace 的字体文件最大是多少M呢

[图片] 今天开发工具突然不可以预览了，昨天（2021/2/25）还是可以的

canvas 2d 动态加载自定义字体在开发工具上没有效果，预览调试字体有效果，请问是什么情况呢 这样字体预览是有效果的，开发工具版本：Stable 1.05.2102010  loadFontFace() {     const self = this     wx.loadFontFace({       scopes: ['webview', 'native'],       family: 'Aemstel',       source: 'url("https://sungd.github.io/Pacifico.ttf")',       success(res) {         console.log(res.status)             },       fail: function(res) {         console.log(res.status)       },       complete: function(res) {         console.log(res.status)       }     });   },
