Questions in general:

1) Is there such thing as a 'marquee-threshold' or 'marquee-delay' or 

2) If main purpose of the marquee is usability - in particular 
readability of lengthly texts on small screens then
neither one of the 'marquee-style' values
do not work quite well in this respect. Ideally initial position of the 
text should allow to read start of the text after loading and
after some delay it should start moving.

Implementation question:

How this marquee works with text-overflow:ellipsis ? Conceptually 
text-overflow:ellipsis and
overflow-style: marquee-line are serving the same purposes 
(text-overflow:ellipsis may trigger
tooltip to be shown to read the whole text).

Wouldn't it be better to add value 'marquee' to the 'text-overflow' 
So 'ellipsis' and  'marquee' will be mutually exclusive?

In this case we do not need 'overflow-style' attribute at all.
