The font of the username isn't scalable

[lissine0]

This is due to using a fixed font size:

Chat/Sources/ExyteChat/Views/MessageView/MessageView.swift

Lines 151 to 154 in 7ed3660

	VStack(alignment: .leading, spacing: 4) {
	if params.showUsername, !message.user.isCurrentUser {
	Text(message.user.name)
	.font(.system(size: 12, weight: .bold))

Note that the user name shown in replies has a scalable font:

Chat/Sources/ExyteChat/Views/MessageView/MessageView.swift

Lines 191 to 193 in 7ed3660

	VStack(alignment: .leading, spacing: 0) {
	Text(message.user.name)
	.fontWeight(.semibold)
