In evolution, if I search for text in the preview pane, the word matching searched-for text (what I type in the "find in message" popup) is erased e.g. if I search for "alias", and the preview pane has the string "not antialiased today", I will see in the preview pane, "not today". This is reproducible every time.
I can't reproduce this with current rawhide builds (and could only sporadically do so with 8.0), so guessing something in the transition between gtkhtml versions fixed it
