[israelKusayev]

• [ yes ] I have searched the issues of this repository and believe that this is not a duplicate.

Reproduction link

Steps to reproduce

change config provider from rtl to ltr

What is expected?

the same behavior like rtl

What is actually happening?

• prefix icon maybe should be in left instead of right (not sure..)
• when typing a lot, the text is under the feedback icon
• icon of some things like (DatePicker, clear icon) is under the feedback icon
• number input -> the text is under the feedback icon (i know because numbers should always by from left to right, but maybe we can give some padding..)
