This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
The wrap property of the HTMLTextAreaElement interface indicates how the control should wrap the value for form submission. It reflects the <textarea> element's wrap attribute. Note that the "hard" value only has an effect when the cols attribute is also set.
See wrap for the possible values. Defaults to "soft".
const textareaElement = document.getElementById("comment");
const oldWrap = textArea.wrap;
textArea.wrap = "hard"; // Add line breaks (CR+LF) during form submission
