What you were doing when the issue happened
Pasting a plain text snippet via a keyword into a new email in Spark email application. I have changed the default font in the Spark email editor from its default (San Francisco 14) to Helvetica 12. However, when I paste the plain text snippet into the email, the snippet uses the default Spark text font and size (which I then have to change).
Whether you were able to replicate it a second time by performing the same action (Update any third-party apps and restart your Mac if relevant)
Yes, this happens every time, though a Reddit user reported that they did not experience this behaviour. They may not have updated to Alfred 5, however (I have).
