Description:
------------
Hello. Starting from php 7.3.2 function mime_content_type doubles the result for xlsx files created in LibreOffice (6.0.7.3). While php 7.3.1 works correctly.


Test script:
---------------
How to reproduce:
1. git clone https://github.com/karser/php_bug_mime_content_type_doubles_result

2. Build the image and see the bug:

docker build --no-cache --build-arg PHP_VER=7.3.2 .

Step 5/5 : RUN php -r "var_dump(mime_content_type('/test.xlsx'));"
 ---> Running in 71f6655ae0ed
string(130) "application/vnd.openxmlformats-officedocument.spreadsheetml.sheetapplication/vnd.openxmlformats-officedocument.spreadsheetml.sheet"


docker build --no-cache --build-arg PHP_VER=7.3.1 .

Step 5/5 : RUN php -r "var_dump(mime_content_type('/test.xlsx'));"
 ---> Running in 27e744a45920
string(65) "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"


Expected result:
----------------
mime_content_type('/test.xlsx') returns "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"

Actual result:
--------------
mime_content_type('/test.xlsx') returns "application/vnd.openxmlformats-officedocument.spreadsheetml.sheetapplication/vnd.openxmlformats-officedocument.spreadsheetml.sheet"

I can reproduce this with the provided .xlsx, but not with
arbitrary LibreOffice .xlsx files.  The behavioral change is most
likely caused by the upgrade to 5.34[1].
