[CLOSED-1131] IE7 QuickTip bug - empty header visible

[grzegorz.borkowski]

See Ext samples: section "Miscellanous", sample named "QuickTips". (I don't post a link, in order to not be marked as "requiring moderation" again)
Open it with IE7. However over rectangle entitled "QuickTip" (last one in first row). When tooltip opens, the gray horizontal line at above of the tooltip is visible - it is because header is empty. Seems like problem relates only to IE7 - on other browsers the line is not visible.
The override we use for this:

if(Ext.isIE7) {
Ext.override(Ext.QuickTip, {
setTitle: Ext.QuickTip.prototype.setTitle.createSequence(function(title) {
if(title === '' && !this.closable) {
this.header.dom.style.display = 'none';
} else {
this.header.dom.style.display = '';
}
})
});
}

I can't reproduce this in IE7 using the 3.3 beta. Can you confirm?

[grzegorz.borkowski]

Those are exact steps to reproduce it.
Open in IE8 the Quick Tips demo from Ext samples (section: Miscellaneous):
http://dev.sencha.com/deploy/ext-3.3-beta2-7080/examples/simple-widgets/qtips.html
Change browser mode to mode IE7 (developer tools -> browser mode: IE7). After page refreshes, hover over the last rectangle (labeled "QuickTip") in the first ("Easiest Tip") row. When tooltip opens, it has small grey line above the "My QuickTip" text.

I see it on IE8 when using IE7 mode, but not in the real IE7. Odd.

I don't have native IE7, but in IETester-IE7 it works ok. Looks like IE7 mode in IE8 it not as reliable as I thought :(

Not at all reliable...
