Bug 17499 – Display issue--extended calendar on delta.com

• Component: Layout and Rendering
• Status: RESOLVED CONFIGURATION CHANGED

[Mark Cohen]

On delta.com in the award calendar path (https://www.delta.com/awards/home.do?EventId=ENTER_APPLICATION, submit cities to search on, calendar appears), the calendar display is extended. The header space above the calendar display is much longer than it should be.

Trying to reproduce this with my local build hit the following assertion failure:

ASSERTION FAILED: m_pendingStylesheets > 0
(/Users/matt/Code/WebKit/WebCore/dom/Document.cpp:2028 void WebCore::Document::removePendingSheet())

This is actually the 2nd time I've hit this ASSERT in the last ~36 hours - the first time was on a site that can't be posted and my initial attempts at a quick reduction failed.

After talking to Mitz, this crash is unrelated to the rendering issue.

I can't use web archive to see what was going wrong around 2007/2008, for example: https://web.archive.org/web/20080819032929/https://www.delta.com/awards/home.do?EventId=ENTER_APPLICATION

gives a response:
"Not Found

The requested object does not exist on this server. The link you followed is either outdated, inaccurate, or the server has been instructed not to let you have it."

and: https://web.archive.org/web/20070625162302/https://www.delta.com/awards/home.do?EventId=ENTER_APPLICATION

gives a response containing the "website had a hiccup"

The current calendar works at: https://www.delta.com/flight-search/book-a-flight?tripType=ROUND_TRIP&EventId=ENTER_APPLICATION.

We can probably close this bug if it is not an issue in rendering.

yes without the initial markup failing, there is nothing which can be investigated.
