Dockerfile editor places the cursor in the middle of the line?

When editing Dockerfiles, the cursor is not where I am typing

This affects Domino 4.4.0 and 4.4.1 and is due to a scaling issue in the 'ace editor'. and Chrome (and may affect Edge browsers too).

You can override the CSS for the ace editor or update to Domino 4.4.2 or later.

1) Install Chrome Extension, StyleBot
2) Add a new style to this for the Domino URL page:

.ace_editor, .ace_editor *{
font-family: "Monaco", "Menlo", "Ubuntu Mono", "Droid Sans Mono", "Consolas", monospace !important;
font-size: 12px !important;
font-weight: 400 !important;
letter-spacing: 0 !important;
}

This will set the font to a monotype which will make the problem disappear.  

Caveat: May not work for all, since Extensions may not be allowed.
