Alice in Wonderland (2010)

Continuity mistake: When Alice leaves to think over Hamish's proposal and chases after the White Rabbit, the heels on her shoes change, but when she falls into the hole the heels are back once again.

Alice Kingsley: This is impossible.
The Mad Hatter: Only if you believe it is.

Trivia: Alice's impending battle on the "frabjous day" with a creature referred to as a "Jabberwocky" is a central plot point, and refers to Lewis Carroll's famous poem "Jabberwocky," from which other characters in the film, such as the Jubjub bird and Bandersnatch, are derived. However, the titular creature of the poem "Jabberwocky" was NOT a Jabberwocky, but a Jabberwock. For whatever reason, the writers of the film chose to call it by the [admittedly similar] title of the poem instead of the actual name of the creature. (For the full text of the poem, see http://www.jabberwocky.com/carroll/jabber/jabberwocky.html).

Question: Why is it that everyone is in the exact same position at the gazebo when Alice left to follow McTwisp when Alice returns? Clearly, some time has passed while she was in Wonderland, so it's confusing how it would still be the same day at around the same time.
