Also make sure word-wrap
is set to normal for IE10 and below.
The standards referenced below define this property's behavior as being dependent on the setting of the "text-wrap" property. However, wordWrap settings are always effective in Windows Internet Explorer because Internet Explorer does not support the "text-wrap" property.
Hence in my case, word-wrap
was set to break-word (inherited or by default?) causing text-overflow
to work in FF and Chrome, but not in IE.
