Human-friendly scenario: * open a thread where a message which ends with an HTML part is followed by another message * make the first message visible * goto the beginning of the second message (first line, first colon) * hit "RET" Result: nothing happens except for "No URL at point" message Expected result: the second message is shown/hidden The root cause is that the HTML part has `keymap' text property set. In particular, "RET" is bound to visit a URL at point. The problem is that `keymap' property affects the next character following the region it is set to (see elisp manual [1]). Hence, the first character of the next message has a keymap inherited from the HTML part.
