Zhi Yan, FWIW, your concern is reasonable. Thanks for raising it. Based on
the Glance v1 strategy, and backward-compatibility concern, maybe we should
mark it as won't fix?

Brian, may I get your opinion on this from a product manager perspective?
Thanks.

Thanks & Best regards,

@flwang, np at all. We can put the input in bug report as a comment
or here anyway, as far as it can let us/me know the gains/advantages on
this "fix".

I'd like to know whether there is a backward-compatibility issue, but seems
it's not a big deal? To keep the image property be case-sensitive is make
sense, at last it is better if we keep same property name as client
provided.

  Zhi Yan,

  I think you're talking about backward-compatibility, right? I would say
  it's possible, just like the v2 is not compatible with v1 against this.
  So that's why I would like to see a bug is opened to track this and then
  we get also some comments from the end user/product manager perspective
  to decide to mark it as won't fix or go ahead.

  One quick question, do you think there is a potential backward-capability
  breaking issue for end user or ISV if we remove existing
  standardizing/normalizing logic? I'd like to know the gains/advantages on
  this "fix".

  thanks,

         For the case-matter issue, I think it's a bug. But as for the - to
        _, I would like to listen Jay's opinion since who is the original
        author. And obviously, it's intentional change.

        Hi Wang Hong adnd Fei Long,

        It's been a long time since I wrote that :) To be honest, I'm not
        sure
        why -- other than just standardizing/normalizing the input, we did
        that.
        Perhaps it had something to do with vendor-specific properties that
        had
        a prefix that used hyphens, but I'm really not sure... perhaps I am
        getting too old :)

        Best,
        -jay
