Keyboard using issue on 26.50 to 26.51

The Android keyboard (GBoard and 3rd party keyboard apps) functionality on the new version of the game and even the previous version, 26.50, has a annoying change to text editing and typing. I'm having serious issue where I can't delete the characters rapidly by holding back button on my keyboard, now you would need to tap rapidly the back button to delete each character.

You can no longer select all or select then manually clicking arrow of the keyboard to select specific line of text to copy them or instant delete them all, and this also applied to all of the items or mechanics (chats, book, ui, command blocks) where you can type. Especially I'm a map creator where I need to type command blocks and chats frequently.

Additional, when you're typing on the chat and you accidentally click or clicking outside the keyboard, the game forced you to close the chat menu. The worst part is there's no draft so if you go back to the chat, the text you recently typed in will be gone, and this is so unplayable for me for somee reason and I think for many players too who uses Android.

I tested those on my other Android phone which is Pixel 7 Pro and the issue also there. Please fix this Issue mojang, this is frustrating.
