Item2259: Anything inside HTML tag BIG gets discarded

Any text pasted into the WysiwygPlugin editor containing the HTML tag BIG will be discarded.

To reproduce,

• create any simple valid XHTML webpage
• include some text inside a <BIG> tag
• view the web page with Firefox
• copy the page and paste it into a new wiki page in Foswiki 1.0.7
• save the page
• observe how the text inside the BIG tag is gone bye-bye

In #foswiki irc:

[10:47] <SinnerP> any area inside <big>....</big> gets discarded
[10:48] <MTempest> SinnerP: Ooh - I see. That is nasty. Please create a task for this, if you haven't already
[10:49] <SinnerP> ok
[10:49] <MTempest> Please mark it applicable to the WysiwygPlugin extension.

Confirmed, raising to urgent.

I do not think pasting in HTML BIG is that normal and for sure we have 100 more html cases that do not survive. It cannot be a release blocker for 1.0.

Downgrading to normal.

WysiwygPlugin discards the content of <big> tags. That is what Foswiki::Plugins::WysiwygPlugin::HTML2TML::Node::_handleBIG does. I do not know why this was done, though.

There are several tags that are discarded - contents and all - and I do not think they should be:

Tag that is discarded	Similar or related tags that are not discarded	Comments
big	small tt i b
caption	thead tbody tfoot
noframes	frameset frame
noscript	script
var	em strong cite kbd samp dfn

Crawford - what breaks if we change WysiwygPlugin to _flatten these tags instead of discarding them?

-- MichaelTempest - 20 Nov 2009

It seems like a mistake. My reaction is that _flatten would be appropriate. Perhaps over the years this is the fragments of an effort to avoid HTML tags in topics, or maybe at some point these tags crashed the WYSIWYG editor of the day?

Moving forward, such efforts should lie in what we're talking about in WysiwygContentPolicies. I'm sorry I can't offer more clear insight than that.

-- PaulHarvey - 30 Nov 2009

Okay - I changed it to flatten the tag i.e. keep the content but remove the tag itself. If the <big> tag is important, then I suggest the tag should be wrapped in a <literal> or <sticky> block.

Fixed in 1.1
