This issue collects known bugs affecting proof input:

Expressions are sometimes unfolded too early. Example: Replicate the proof of https://slate-prover.org/libraries/hlm/Essentials/Functions/Generalized%20restriction%20preserves%20injectivity.
The text "Trivial" is sometimes omitted incorrectly when editing a proof, and sometimes "No proof" is displayed instead. Examples: https://slate-prover.org/libraries/hlm/Essentials/Sets/Intersection%20is%20idempotent, https://slate-prover.org/libraries/hlm/Essentials/Numbers/Natural/Left-addition%20of%20zero%20is%20neutral
It seems that embeddings are sometimes applied to terms that are not actually elements of the embedded subset. Example: https://slate-prover.org/libraries/hlm/Essentials/Numbers/Integer/Power%20base%20product%20law ("Prove by definition")

We should create regression tests for these bugs, except maybe for those that purely affect rendering.
