Clear all markup confirmation unclear

[wesdean]

The message displayed when clearing all markup is unclear.
google-maps-markup/component.js:26
const clearAllConfirm = 'Clearing results will persist the changes, if you want to save a copy of the results please copy the url before clearing the markup.';

I believe that "will persist" should be "will not persist".
Additionally, in our specific implementation the markup is not saved in the URL, but in a separate place on the site. I believe that a message such as the one below would be more clear and universally applicable.

Perhaps a message such as this would be more clear.
"Markup is unsaved. Do you wish to continue clearing all markup?"
