Tuckey use-query-setting exclusion - url-rewriting

Question

I am using Tuckey rewrite filter to make some rules to map urls. For example, I got the following:
<?xml version="1.0" encoding="utf-8"?>
<urlrewrite use-query-string="true">
<rule enabled="true">
<note>Do not process URLs targeting fonts</note>
<from>/*fonts*</from>
<to last="true">-</to>
</rule>
<rule enabled="true">
<note>Do not process calls to images</note>
<from>/*images</from>
<to last="true">-</to>
</rule>
<rule enabled="true">
<note>Process the rest of the links </note>
<from>/(.*)$</from>
<to type="passthrough">/</to>
</rule>
</urlrewrite>
What the rules above allow me to do, is to passthrough anything with /fonts and /images and everything else (catchall), gets redirected back to the homepage.
I would like a rule to not process any query parameters and let it passthrough as is. I tried various regex strings, including
<rule enabled="true">
<note>Do not process calls to /?*</note>
<from>^/(.*)?</from>
<to last="true">-</to>
<rule>
but they did not work.
Essentially any URL, such as https://example.com/promo/def get rewritten back to / (which is working).
What is not working is that https://example.com/promo/?def gets rewritten back to / and not being passed through. That's not working right now.
Thanks in advance.

You should explicitly tell tuckey filter that you want your query string to be appended to the target URI.
It is possible by using qsappend attribute in your <to> property.
<rule enabled="true">
<note>Do not process calls to /?*</note>
<from>^/(.*)?</from>
<to qsappend="true" last="true">/</to>
<rule>
If you use version below 4.0, there is an alternative solution with appending query-string to the target URI explicitly.
<rule enabled="true">
<note>Do not process calls to /?*</note>
<from>^/(.*)?</from>
<to last="true">/?%{query-string}</to>
<rule>
