Still having issues with no space in text area - 9.18.1

Anyone still running into the issue with no spaces in text areas.  I believe this was a known bug sometime around 9.5 (per a previous post / docs ( Forum Post , 9.6 Release Notes, 9.11 Release Notes ) but we experiencing this issue in 9.18.1.   Text box works correctly, but we run into the issue when using text area in a popup.    This is the case even if I modify HTML

Solved.  The textbox was nested inside of a datagrid2.  Removing the onClick action of the datagrid solved the issue.
