I work within JOOMLA (3.10) with JCE 2.9.16.
Steps to reproduce the problem:
Open an existing article with an existing table.
Move cursor on a table-row. Click right mouse button and select "Table row properties".
Change a property of the selected table row: here: change background colour to any other colour (here: #eff2f5")
Click on button "Insert"
The table row is changed as per step c), but moves to the TOP of the table.
If I want to change the properties of a table row, the table row may not change it's position.
Thank you and
