It is an exceptional case but still worthy of attention, I feel.
Currently on EL&U, there is a question about a single word in Joyce's novel, “Finnegans Wake”
Meaning of “bababadalgharaghtakamminarronnkonnbronntonnerronntuonnthunntrovarrhounawnskawntoohoohoordenenthur-nuk!” The title is so wonderfully long, a scrollbar is necessary in order to read it in its entirety.
The post in its full version
I am using Chrome, version 84.0.4147.105., the font is enlarged to 110% but the "problem" persists if reduced to its original size.
If there is a maximum number of characters allowed in a title, as I imagine there must be, why should a scrollbar appear? Is there a solution so that a scrollbar is not needed?
Searching through the Meta archives revealed that a question title cannot contain more than 150 characters: "Title cannot be longer than 150 characters" - why doesn't the field have an input limit or a character count then?
The EL&U title is 115 characters long, so well within the limit, but the title breaks after the hyphen in “thur-” Theoretically, does that mean a title consisting of 150 characters with no spaces or punctuation marks would not be interrupted?
(The EL&U theme fails to keep pace as the single-word rolls on undisturbed.)
