Comment:

 First pass. Initially tried to have just one live region and dynamically
 update the `aria-live` attribute switching its value as seen in other
 implementations but after some testing I'm not convinced all screen
 readers out there can get that right. Decided to go with two separate live
 regions.
 The patch also changes the `aria-relevant` attribute to the default value
 `additions text` and introduces one new function to clear the live regions
 in order to allow repeated strings to be read out.

 Tested and it's functional, would appreciate some devs eyes about best
 practices, code cleaning, etc.
