PHP 7.3 Bug: "continue" targeting switch is equivalent to "break". Did you mean to use "continue 2"

Using the file core-module in a BrowserTestBase-PHPUnit tests results with PHP 7.3 in failure like so

There was 1 error:

1) Drupal\Tests\genosharing\Functional\LoadTest::testBasicPages
"continue" targeting switch is equivalent to "break". Did you mean to use "continue 2"?

/home/rainer/src/gs/web/core/modules/file/file.module:898

PHP 7.3 has depreciated "continue", see here: https://wiki.php.net/rfc/continue_on_switch_deprecation

Change the "continue" statements in file.module's switch from line 893 to "continue 2" fixes the problem (for PHP 7.3).
