In the latest version of Document Viewer (5.9.6) running on Deepin 20.2.4, the "New Tab" button has broken spacing. How much space is between the button and the tabs changes depending of how many tabs are open, and gets way too big. There are no funcionality bugs here, it just looks very strange and inconsistent. Restarting does not fix the issue and it happens every single time.

在Deepin 20.2.4上运行的最新版本的文档查看器（5.9.6）中，“新标签”按钮的间距已损坏。 按钮和选项卡之间有多少空间会根据打开的选项卡数量而变化，并且会变得太大。 这里没有功能错误，只是看起来很奇怪和不一致。 重新启动并不能解决问题，而且每次都会发生。

Here is an example of the spacing with different numbers of tabs. Pay attention to the "New Tab" button:

(这是具有不同标签数量的间距示例。 注意“新标签”按钮：)
