Interestingly, this bug affected and still affects almost all web browsers. All but Internet Explorer, though.
In August 2010, far from being fixed, the very same bug got marked as "INVALID" as "this feature is no longer present in HTML5, and has not been implemented in browsers other than IE". In other words "don't bother us as this is not even a bug any more: we are working on the next forthcoming standard, whenever will it come".
Or "none else but IE has it, so we don't mind, even if everyone else is just me"
A tsunami of angry comments flooded bug #915 entry until a couple of days later the bug got turned back to "NEW" (yes, 12 years new).
This seems to follow a trend in the technology development policies for a number of projects, not just open source software.
As soon as the development steering board decides something new (like HTML5 or the next Ubuntu release) requires the focus, suddenly unfinished or unfixed old stuff (HTML4 compliance or the current official) goes to the attic to be forgotten as outdated or uninteresting.
Apart of the humoristic implications for this very case, I'd like to ask slashdotters about their point of view and possible suggestions."
