More zoom issues

This image is made of two screenshots : on the right hand side, a screenshot of http://lemonde.fr resized to a 240px width. On the left hand side, a screenshot of exactly the same page with a zoom factor applied so the whole content fits into a 240px vertical gutter (think sizeToContent()). Many issues here :
  • the font-size issue I already reported
  • much more important, the radio buttons and checkboxes are not resized, completely horking some sections of the page
  • on the left hand side of the image, in the middle, you have this block of two columns od headers that is zoomed out into a block of only one column of headers and a white space at the right of the column.
  • the original resized screenshot is 240x949px. The screenshot of the zoomed out view is 240x1076px.

Again, as a a result, the position (think offsetLeft and offsetTop) of a given element changes between two values of zoom. To give a concrete example, this is a severe blocker for the mobile world to implement something like the thumbnail view/zoom view of the iPhone where the thumbnail would be a LIVE zoomed out page (with video playing and dynamic effects running) and not only a screenshot.

Update: filed under bug 400364.

Daniel, I decided to post about this in my own blog:

Summary: there are two ways to do zooming and we haven't implemented the one you want, but we will be able to later.

Actually, the iPhone changes the font size dynamically when you zoom. It does a relayout. It's hard to notice, though.
