V-show takes higher priority than style attribute

Editor assessment

fix(v-show) states that v-show now takes priority over the style attribute, an understandable behavioral statement with the correct scope and type. The header is imperative, unterminated, and includes the pull request reference, while the body closes issue #2757 in a well-formed footer. The reasoning behind the priority decision is not explained, but the change is narrow and the behavior is self-describing. Clean and publishable, with only the absence of motivation to note.
