[0.12.1]ReuseTabsRouteView style

[shuaqq2004]

从0.11.0升级到0.12.1之后，ReuseTabs模式下排版出现错误。
After upgrading from 0.11.0 to 0.12.1, a typesetting error occurred in ReuseTabs mode.

在2个及其以上的标签出现的时候，未能隐藏掉之前的tabs.
Failed to hide previous tabs when 2 or more tabs appear.
在tabs之前切换的时候，新增了以下style
When switching before tabs, the following 'style' is added

visibility: hidden; height: 0px; overflow-y: hidden;

应该采用 display:none的方式。
You should use display:none
