In Ext Modern 6.5.1, calling disable() on toolbar control does not disable the toolbar or the items in it. The same problem does not happen in Classic.

Fiddle: https://fiddle.sencha.com/fiddle/28fe/preview

Steps to replicate : Browse the fiddle, tap button1, this should disable the toolbar button - btn1, but it will not, tapping btn1 will fire its handler which shows an alert message.

Thank you,
