Description

The element tree might be too deep.

This issue causes problems for people who rely on a screen-reader and keyboard for navigation because traversing elements will seem to take a long time and may appear cyclic.

Possible causes

  • Multiple elements or their parents are custom controls that do not implement tabbing correctly. For example, the MSAA State property is not updated correctly.
  • The application UI is overly complex.
