  -When using tool windows in undocked mode, the preview will overlap with the tool window.
  +When using tool windows in the undocked mode prior to plugin version 0.35.1, the preview will overlap with the tool window.
   See issue https://github.com/asciidoctor/asciidoctor-intellij-plugin/issues/751[#751] for details.
  -It seems to be rooted in the platform.
  -All plugins that use the JCEF preview (including JetBrains's Markdown plugin) are affected.
  -Please vote for the following issues to raise attention for this problem: https://youtrack.jetbrains.com/issue/IDEA-257702[IDEA-257702] and https://youtrack.jetbrains.com/issue/IDEA-252845[IDEA-252845].
   
   The JCEF preview doesn't support the IntelliJ proxy configuration prior to 2021.1.
   Configuring a proxy for JCEF requires an IDE restart.
  -Therefore, remote images in the preview might not show if you are behind a proxy.

   See '`xref:faq/jcef-no-proxy-support.adoc[]`' for more information.
   
   Once a JCEF preview is open in a project, it now and then brings the focus to the project when editing files in a different window in IntelliJ 2020.2.

  == When you can use JCEF preview
  
  JCEF preview is only available from IntelliJ 2020.2+ and plugin version 0.31.x.
  It requires that the user runs on the pre-packaged JetBrains OpenJDK 11.
  
negative.code: === Selecting a different JetBrains JDK using the "`Choose Runtime`" plugin
  
  This is recommended for Android Studio 4.2 and 2020.3+ that doesn't ship with either JavaFX or JCEF support.
  Watch https://issuetracker.google.com/issues/159933628[this issue] in Android Studio's issue tracker for progress.
  
  JavaFX preview that used to work with Android Studio 4.0 will not work with Android Studio 4.2 as it doesn't package the necessary classes in the IDE.
  Therefore, follow these steps to enable JCEF preview for Android Studio.
