Breakpoint are not loaded correct when DevTools is active

This happens quite often: when I load a page with the DevTools active (inspector panel open) where I've set Tailwind breakpoints these breakpoints are not respected.

For example, if I have an element set to be hidden on mobile and shown on medium breakpoint like this:
```html

```
When I load this page with viewport wider than the medium breakpoint and the DevTools active the div is hidden. Even if I reload the page. Only when I click on the div in the elements tab it is drawn, or if I close the web inspector and reload the page.

没有指定源文件、测试或入口点。在 DevTools 打开的情况下，使用提供的 hidded md:flex 示例，并采用宽于 medium breakpoint 的 viewport 进行复现；将初始渲染与选择元素或关闭 DevTools 后重新加载的结果进行比较，然后定位 breakpoint 加载路径，并为初始渲染添加覆盖测试。
