I have a video recording of the bug: https://youtu.be/dw8YDnO5njs
I have a RowFormatting event; if there is an error, I set the row Red and debug.writeline 'Error'. If the value is changed, I make it green and write out 'Changed'.
See the video; here's the debug output for all RowValidation events:
- dragercode: Ok
dragercode: Ok
dragercode: Ok

uitdienst: Changed
status: Changed
opmerking: Ok
wisselkastgroep: Ok
wisselkastvak: Ok
kledingkastgroep: Ok
kledingkastvak: Ok
emailadres: Ok
Yet, you see that 'uitdienst' is just white. When I mouse-over or click, it shows up with the green color.
