Sitecore.Speak.Bootstrap3 是问题所在。在 7.5 中，体验编辑器是使用此 SDK 自定义的。我们在升级过程中忘记了它。升级进展顺利，但并未改变 Core DB 中体验编辑器的自定义。因此出现了这个问题。我们通过从 8.2.3 的 vanilla 安装中获取相应的项目 (21E86498-6C8E-4F3B-83F2-B49E5E0ABE16) 并安装升级的 sitecore 包来解决它。

我们通过在 Core DB 中搜索“Sitecore.Speak.Bootstrap3”文本获得了项目 (21E86498-6C8E-4F3B-83F2-B49E5E0ABE16)。
