After upgrading from Magento 2.2.2 to Magento 2.3.3. While generating static content with command "php bin/magento setup:static-content:deploy -f" it updates all the files in pub/static folder except mage folder and files from
"vendor/magento/magento2-base/lib/web/mage"
to
"pub/static/frontend/Theme/Theme_Name/en_US/"
I am using following command
php bin/magento setup:static-content:deploy -f
