Hi Friends,
I come across one issue while upgrading from AEM 6.3 to AEM 6.4.
Richtext is not working if we have tabs in component dialog in AEM 6.4. It perfectly working fine in 6.3 but not in 6.4. I'm getting below error.
all.js:2827 Uncaught TypeError: Cannot read property 'sourceEditMode' of undefined
