filtering tab-completion candidates as you type doesn't obey CASE_INSENSITIVE option

If I type the following in CommandBox and hit tab:

CommandBox> cd _
.git/               JRE_9/              bradtest/           coldbox-platform/   foo/
JRE/                bar/                cborm-shell/        directory=          lib/

You can see that the candidates include all of the folders in that directory. Now, if I type an upper case "J", the list filters to "JRE" and "JRE_9". However, if I type a lowercase "j", then all the candidates are removed. I need this to be case insensitive-- at least on Windows. Setting the CASE_INSENSITIVE has no effect on this.
