if php.ini has a too low upload_max_filesize, the system correctly issues a warning and instructions to correct php.ini BUT omits the required post_max setting requirement

Steps to reproduce the issue

upload a file with administrator/index.php?option=com_installer&view=install

Expected result

when following instructions, php.ini upload_max_filesize will function

Actual result

at the very next occasion, Joomla will issue a new warning

Warning PHP Upload Size bigger than POST size.
The value of the upload_max_filesize in the php.ini file is greater than the post_max_size variable. ...

System information (as much as possible)

this new warning can be AVOIDED by COMPLETING THE INSTRUCTION to set both the upload_max_filesize AND the post_max_size variable to the same value.
