1682313 - Disconnected cloned textarea does not fire select events

Status: RESOLVED FIXED

(Core :: DOM: Selection, defect)

Description

[Kagami Rosylight [:saschanaz] (they/them)]

textarea = document.createElement("textarea");
textarea.textContent = "Foo";
clone = textarea.cloneNode(true);
clone.onselect = console.log;
clone.select();

Expected: Both should fire a select event
Actual: Only the first one should fire one

Cloning the element does not properly set the maxLength in SelectionProperties.

Attachment: Bug 1682313 - Make sure mMaxLength exists in SetSelectionRange

Cloning a textarea element without a dirty value flag does not call SetValue() and thus gets no max length. This makes sure it always gets one before setting selection range.
