Prevents fast double navigate

Browse Source 
This puppeteer script [likely will] crash the brower:

page.goto(baseURL + '/campfire-commerce/');
await page.goto(baseURL + '/campfire-commerce/');

The quick double-navigation means parse_state remains .pre and thus the page
isn't reset. We introduce a new load_state, .waiting, which can be used to
detect this state.
