模板第一个块直接无法预览

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

斜杆调出模板面板后，第一个模板不会直接显示预览内容

需要键盘上下移动后才能显示预览内容，或者鼠标移动到选项才能显示预览

Expected result

建议默认预览第一个块
