The overt bugs (where the query itself, not the text I typed, is displayed - and where the page isn't reloaded properly upon restarting the app) are solved
But although the current behaviour matches safari, I don't think it's the ideal design. What if I want to copy only a certain portion of the URL? I need to tap share > copy > paste it somewhere > select what I want or edit it > copy again. Pretty roundabout. Besides copying a certain portion of the URL, maybe I need to change a TLD on a search engine, or add a specific parameter to the query.
So I vote for an option to "Always show full URL in Address Bar", or perhaps an additional context menu item when tapping on text in the Address Bar next to "Copy": "Copy full URL"
