Now and then in the displayed chat messages the at the begin of a new line after a line-break in the middle of a word/url the first character is missing. Could not yet see a pattern though for when it happens. Even more, for the very same word/url it might happen or not depending on where the line-break is enforced, see attached example. Reproducible: Sometimes
Created attachment 98522 [details] Char missing on line-break in url
Created attachment 98523 [details] Char not missing on line-break in url at different position
