回复: [edk2-devel] [PATCH V2] MdeModulePkg/BootManagerMenuApp: Limit string drawing within one line

["gaoliming" <gaoliming@byosoft.com.cn>]

Zhichao:
  With this change, the same boot option will be displayed differently in
BootManagerApp and BootManager Page. Is it the designed behavior?

  Besides, please remove change-id from the commit message. 

Thanks
Liming
