Fix `e` character logic.

Editor assessment

The subject, Fix `e` character logic, is terse to the point of obscurity: it names the character involved in number-input entry but not what was wrong — presumably exponent handling — so the reader must infer the defect class. The number-input scope is a proper component noun, and the fix type matches. The doubled fix wording adds redundancy. There is no body to explain the failure. No footers appear. Decodable for maintainers familiar with numeric-entry quirks, but opaque to everyone else.
