-* The way `assert_select` works has changed; specifically a different library
- is used to interpret CSS selectors, build the transient DOM that the
- selectors are applied against, and to extract the data from that DOM. These
- changes should only affect edge cases. Examples:
- * Values in attribute selectors may need to be quoted if they contain
- non-alphanumeric characters.
- * DOMs built from HTML source containing invalid HTML with improperly
- nested elements may differ.
- * If the data selected contains entities, the value selected for comparison
- used to be raw (e.g. `AT&T`), and now is evaluated
- (e.g. `AT&T`).
