/**
 * Computes the *expected* ARIA accessible name for argument element based on [accname-1.2
 * specification](https://www.w3.org/TR/accname-1.2/). Implements a subset of accname-1.2,
 * and should only be used for the Datepicker's specific use case.
 *
 * Intended use:
 * This is not a general use implementation. Only implements the parts of accname-1.2 that are
 * required for the Datepicker's specific use case. This function is not intended for any other
 * use.
 *
 * Limitations:
 *  - Only covers the needs of `matStartDate` and `matEndDate`. Does not support other use cases.
 *  - See NOTES's in implementation for specific details on what parts of the accname-1.2
 *  specification are not implemented.
 *
 *  @param element {HTMLInputElement} native <input/> element of `matStartDate` or
 *  `matEndDate` component. Corresponds to the 'Root Element' from accname-1.2
 *
 *  @return expected ARIA accessible name of argument <input/>
