Subject: Fix backspace deletion of selected items with change tracking
X-Git-Url: https://git.lyx.org/gitweb/?a=commitdiff_plain;h=2cec20fa28262d7d87150c588c42405dafd8cc85;p=features.git

Fix backspace deletion of selected items with change tracking

Move cursor at beginning of selection after deletion. Else backspace
operation gets stuck in a loop (tries to remove the selection again
and again).

This also fixes backspace deletion of insets with confirmDeletion() == true.

Fixes #11630
