Symfony version(s) affected: 5.2

Description
I have symfony/mailer and symfony/mailjet-mailer installed.

My composer.json contains this.

{
#...
        "symfony/mailer": "5.2.*",
        "symfony/mailjet-mailer": "^5.2@dev",
#...
}

My .env contains:

MAILER_DSN=mailjet+smtp://xxx:yyy@default

I get the following error:

The "mailjet+

So if you happen to insert invalid version string when requiring package, it will still write it into composer.json and nothing works after that. So for example; composer require phpunit/phpunit:"8.3.3 as ^8.3"

My composer.json:

{
    "require": {
        "phpunit/phpunit": "8.3.3 as ^8.3"
    }
}

Output of composer diagnose:

$ composer diagnose
        

According to http://manual.phpdoc.org/HTMLframesConverter/default/

@property shows a "magic" property variable that is found inside the class.

The property is presumed to be available for both read and write operations. If the property is read-only, you should use the @property-read tag instead. If the property is write-only, use @property-write.

Example:

/**
 * show

The ability to set the language on the user creation form could be something useful on a multi user environment.

Under the 'Theme' settings tab you can upload images. It would be great if vector images can be added so it can scale without causing artifacts.

When creating or editing a relationship, we should group the relationship type list with the same tag as on the contact page (Love, Family, Other kind, ...), i.e. with an element.
