Comment 41 for bug 425979

I believe this is intended behavior of GRUB on UEFI, and has been like this for years:

> "During boot, the system will check the SHIFT key status. If it cannot determine the key status, a short delay will enable the user to display the menu by pressing the ESC key."

As "cjwatson" said on the Debian #902928, I also don't believe UEFI allows us to easily check modifier state, as such I am not sure if any course of action is appropriate here.

Setting this to "Incomplete" to leave time for people to propose any action items, and downgrading severity to "Wishlist" (seems appropriate given this was open for 15 years).
