file upload blocked by owasp 3.0 rules

Hello RStudio,

i have an application which uploads a csv file. unfortunately fileInput is submitting a ajax call with header content-type as "application/octet-stream" https://github.com/rstudio/shiny/blob/72f86dac27eb230327fbd89fd2f892d0cd0355a9/srcjs/input_binding_fileinput.js#L110 which is blocked according to owasp rule https://github.com/SpiderLabs/owasp-modsecurity-crs/issues/657 , is there any way we can avoid this?
