- Web Worker Profiling:
- When profiling an application with the F12 developer tools, you will only see activity from web workers that were started after you began profiling. To work around this issue, make sure the profiler is started before the worker(s) you want to profile.
- Placing comments before the DOCTYPE declaration incorrectly puts IE10 into quirks mode.
- Platform Preview setup shows an error dialog if you have open windows of older Platform Previews:
- If you have open windows of older Platform Previews running while you install the latest available Platform Preview, you will see an error dialog during setup. To avoid this issue, please close all open instances of the Platform Previews and re-run the newest Platform Preview installer.
- Platform Preview Build opens links to *.EXE files as text:
- Description: When you click a link to an executable (.EXE) in the Platform Preview, it will open in the Platform Preview as a text file. To work around this issue: Right click the link and choose "Save Target As..." to save the linked file to your machine, after which you may run it. For more information see connect issue 556100.
- Downloads initiated by script do not function:
- There is no Information Bar (aka Gold Bar) in Platform Preview. As a result, downloads initiated by script will not function. Files can be downloaded using the “Save Target As…” in the right-click context menu, by clicking on hyperlinks to files, and by typing a download URL in the Open dialog (Ctrl+O).
- Upgrading the Platform Preview Build turns the taskbar pinned icon into a blank page icon:
- When a user upgrades from one version of the Platform Preview Build to the next, the taskbar pinned icon to turns into a blank page icon. As a workaround you can right click the icon on the taskbar and select "Unpin this program from taskbar". Open the Start Menu, right click the newly installed Internet Explorer Platform Preview under All Programs, and click "Pin to Taskbar".
- CSS Grid and CSS Flexbox do not currently support anonymous text blocks:
- A temporary workaround is to wrap such blocks with an explicit element.
- Layering is not currently supported in CSS3 Grid
- The CSS calc() function is not currently supported for CSS3 multicolumn properties
- Absolutely positioned elements contained within a multicolumn element may be positioned incorrectly if they are encountered after the multicolumn fragment in which they should be positioned
- Borders may be drawn outside of the border box when specified on a CSS Grid item
