Symfony version(s) affected: 4.3@dev

Description
Having this issue after upgrading from 4.2 to 4.3@dev

How to reproduce

1. ensure php.ini contains:

xdebug.file_link_format = "phpstorm://open?file=%f&line=%l&/docker/path/to/app>/host/path/to/app"

2. execute in running container with app :

bin/console debug:container

3. get an Exception

In ParameterBag.php line 100:
The parameter "templating.helper.code.file_link_format" has a dependency on a non-existent parameter "f&line=".

Possible Solution
¯\_(ツ)_/¯

Additional context
framework.ide parameter is not configured in SF config.
