bug: Autogrow should reset back to number of rows specified when text is cleared

[AVatch]

Bug Report

Ionic version:

[x] 4.6.1

Current behavior:

Create an ion-textarea with autoGrow set to true. Then on submit or another action set the value to an empty string. The textarea does not revert to its original height.

Expected behavior:

The textarea should reset to the height specified by rows or just 1 row. (This worked in 4.5.0)

Steps to reproduce:

hello, I discovered that if you put this css, it helps to return to the original size when you delete the characters one by one

in the global css file

    .native-textarea.sc-ion-textarea-md{
       border-width: 0.5px !important;
       border-top-style: solid !important;
    }

and you can make it transparent

    .native-textarea.sc-ion-textarea-md{
        border-top-color: transparent;
        border-width: 0.5px !important;
        border-top-style: solid !important;
    }

You can also use angular Auto-resizing textarea in your ionic application

English is not my native language, if something is not very clear, let me know
