[BUG] messages not displayed correctly with rtl and ltr languages in compact view

a message starting with an RTL language following an LTR language is displayed incorrectly
but only in compact mode.

you can swap between cozy and compact in:

settings > appearance > message display

for example the sentence (screen shot because this website messes it up too):

is displayed (improperly) like this:

but with cozy view mode it is displayed correctly:

inspecting the CSS in the developer tools shows that the css difference between the two cases is that the cozy configuration has a "unicode-bidi: plaintext" property 
but the compact doesn't.
