Can't I adjust the input method size with Glory V 10 one-handed keyboard?

After turning on the one-handed keyboard switch in Settings > Intelligent Assistant > One-handed Operation, you can manually adjust the size of Huawei's input method to make it more suitable for one-handed typing, but when you increase or decrease the input method to a certain size, you can't continue to adjust it.

Reason:

In order to prevent the input method panel from occupying the mobile phone screen because it is too large, or the layout is too small and easy to touch by mistake, the system will limit the adjustment range of Huawei input method under a one-handed keyboard to avoid being too large or too small. This phenomenon is not a mobile phone failure, please feel free to use it.
