描述

From https://github.com/whatwg/html/pull/1790#issuecomment-250752410:

@zcorpan The list given above doesn't look complete to me. It's missing:

  • shadowOffsetX
  • shadowOffsetY
  • shadowBlur
  • lineWidth
  • miterLimit
  • setLineDash
  • lineDashOffset

at first glance.

There might be more missing as this is from Firefox implementation which may not have everything implemented yet.

We also forgot to file a WPT issue.

研究方向
Review the HTML Canvas specification to identify all member attributes that need handling of infinite and NaN values. Check the referenced PR #1790 and its comments for context. Additionally, file a new issue in the Web Platform Tests repository to add tests for these cases.
