Title: Enum values that ignore naming conventions in HTML Standard
Tracked: >-
The CanvasTextRendering names are inherited from SVG and seem widely deployed;
flipY seems widely supported (according to WPT)
Repo: 'https://github.com/whatwg/html'

While crawling HTML Standard, the following enum values were found to ignore naming conventions (lower case, hyphen separated words):

• The value "optimizeSpeed" of the enum CanvasTextRendering does not match the expected conventions (lower case, hyphen separated words)
• The value "optimizeLegibility" of the enum CanvasTextRendering does not match the expected conventions (lower case, hyphen separated words)
• The value "geometricPrecision" of the enum CanvasTextRendering does not match the expected conventions (lower case, hyphen separated words)
• The value "flipY" of the enum ImageOrientation does not match the expected conventions (lower case, hyphen separated words)

See Use casing rules consistent with existing APIs in Web Platform Design Principles document for guidance.
