Hello! I tried to set some global variables for all the email builders we have. Its a user field i want to render in the mail, and the user object is based on the 'to' address. The code on it self works and the variables are set correctly, but when I was testing the email - the twig variable were not converted in the given string.
After some digging around i found that the Drupal\symfony_mailer\Plugin\EmailAdjuster::BodyEmailAdjuster has an `$email` variable, but the getVariables() do not have the variable set from the hook. Yet the hooks are fired before the adjuster.

I believe it is a matter of timing.
BodyEmailAdjuster->build() runs with weight 400. It saves the variables into #context.
Your hook likely runs with default weight of 500. If you change your weight to 300 it should work.
