The problem of Mini Program textarea in setting to overflow:auto element

A problem encountered when developing WeChat Mini Programs is that if you put textarea in an element set to overflow:auto , the input text will slide with the page. The current page layout is as follows:

but if you do not set the overflow attribute of the parent element, it will be like the image above, the text covers the submit button, and the button is located at the bottom through fixed . After checking the information, this is a problem that Mini Program has always had, and it seems that it has not been fixed so far. I would like to ask all the experts, is there any way to avoid this pit?
