What is the use-case or motivation for changing an existing behavior?

Text can be long in options, the user should not have the option text hidden from them.
For translated text that is longer than the source text this can happen more frequently.

Which versions of Angular, Material, OS, TypeScript, browsers are affected?

Latest

Is there anything else we should know?

In a select in multiple selection mode, the option text is entirely hidden for long options on at least Firefox and IE 11.

Firefox 56

Chrome 61 is almost good (two dots hidden)

That is a separate issue from the one being discussed here @dixy, but thanks for the report. It should be fixed by #7857.
