Strings which contains hyphen in the title are breaking
Title: MEMORY MODULE P/N 2040696-0501 TO -0502 UNIT DASH NUMBER CHANGES FROM 3614291-4501

In Browser title should break like below:

I tried css code like word-wrap:break-word or overflow-wrap:break-word but none of the css properties not working.

h6{word-wrap:break-word} // this code not working.
h6{overflow-wrap:break-word} // this code not working

I need only css code to resolve this. Please help me if anyone knows or already fixed this kind of issue.
