Created attachment 8826943 [details] firefox-line-height-bug.png User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_2) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/55.0.2883.95 Safari/537.36 Steps to reproduce: I applied specific styles to :first-letter pseudo class to achieve drop-cap typography effect. To have drop-cap properly wrapped by text, I applied float:left style to it. Actual results: The result is that Firefox ignores line-height definition, making it impossible to properly align drop-cap with the rest of the text (see screenshot attached). Expected results: Line height should have effect over floating box height.
Provide a testcase, please.
