rewriteRule when relative is malfunctioning when depth greater than 1

[gpickin]

Rewrites are getting confused from rewrite match to lucee request being executed.
Same rewrites work on Apache

With the following rule.
RewriteRule ^(.*)$ index.cfm%{REQUEST_URI} [QSA,L,NS]

Hitting a url of /cbadmin is rewritten as /index.cfm/cbadmin correctly

Hitting a url of /cbadmin/foo is matched by the rules and says its rewriting as /index.cfm/cbadmin/foo
The actual request is hitting Lucee as:
/cbadmin/index.cfm/cbadmin/foo

If the rewrite is set as /index.cfm it will work because if that leading slash is missing, some code somewhere is making it relative to the "folder" it thinks it's in.

This works RewriteRule ^(.*)$ /index.cfm%{REQUEST_URI} [QSA,L,NS]
But only if you aren't using a subfolder.

If you have /app/index.cfm and you hit /app/cbadmin/ it would fail if you have the rule with /index.cfm

with this rule: RewriteRule ^(.*)$ index.cfm%{REQUEST_URI} [QSA,L,NS]
hitting this url - http://127.0.0.1:53575/app/monkey/lion/tiger
I see this error

[DEBUG] requested: '/app/monkey/lion/tiger'
[DEBUG] urlrewrite.UrlRewriter: processing request for /app/monkey/lion/tiger
[DEBUG] urlrewrite.RuleExecutionOutput: needs to be forwarded to index.cfm/app/monkey/lion/tiger
[DEBUG] urlrewrite.UrlRewriter: rule is last
[WARN ] responded: Status Code 404 (/app/monkey/lion/index.cfm)

if i have the trailing / like http://127.0.0.1:53575/app/monkey/lion/tiger/
then i see this error

[DEBUG] requested: '/app/monkey/lion/tiger/'
[DEBUG] urlrewrite.UrlRewriter: processing request for /app/monkey/lion/tiger/
[DEBUG] urlrewrite.RuleExecutionOutput: needs to be forwarded to index.cfm/app/monkey/lion/tiger/
[DEBUG] urlrewrite.UrlRewriter: rule is last
[WARN ] responded: Status Code 404 (/app/monkey/lion/tiger/index.cfm)

If i make the rule have a slash RewriteRule ^(.*)$ /index.cfm%{REQUEST_URI} [QSA,L,NS] then it works from the base.

[DEBUG] requested: '/app/monkey/lion/tiger/'
[DEBUG] urlrewrite.UrlRewriter: processing request for /app/monkey/lion/tiger/
[DEBUG] urlrewrite.RuleExecutionOutput: needs to be forwarded to /index.cfm/app/monkey/lion/tiger/
[DEBUG] urlrewrite.UrlRewriter: rule is last

Should we require the / at the start?
