Fix for making popup size proper when we have 'Block third-party cookies and site data' checkbox enabled.
string for IDS_COLLECTED_COOKIES_BLOCKED_THIRD_PARTY_BLOCKING_ENABLED
is not getting wrapped, so the popup size is getting set to largest string size
so making big poup un-necessarily.
Now string will get wrapped by the size of the treeviewwidth so we will
get the same size of popup when checkbox is checked as well as when checkbox is not checked cases.
