Capitalizing first letter of error message cause disjoining first Persian letter

[iriman]

This is caused by

iD/css/80_app.css

Lines 2618 to 2620 in 6ff381c

	.error-details-description-text::first-letter {
	text-transform: capitalize;
	}

A workaround is to add this rule

[dir="rtl"] .error-details-description-text::first-letter {
    text-transform: none;
}

But i'm not sure if all RTL languages don't have capital letters!

Thanks @iriman - I added the rule. We knew this was kind of a hacky rule to begin with, so we might need to find a better way to localize strings like these.

For anyone curious - it's about localizing messages like "This highway is missing a maxspeed tag". We split out the "this highway" part into a separate translatable string so that we can replace it with the actual name of the highway when/if iD knows it. We don't know for sure whether the "this highway" part will be at the beginning of the string, so we use a CSS rule to capitalize the first letter of the message.
