最新版搜索面板中搜索框的内容无法再选中，只能触发窗口拖拽

Is there an existing issue for this?

• I have searched the existing issues

Can the issue be reproduced with the default theme (daylight/midnight)?

• I was able to reproduce the issue with the default theme

Could the issue be due to extensions?

• I've ruled out the possibility that the extension is causing the problem.

Describe the problem

如图，只能ctrl+a选中文字，或者从很微妙的搜索框的左上角选中文本。

Expected result

希望修复该问题
