Need some suggestions, looking more of a work around for prod issues. We have Sencha ExtJS version 5.1.1 application with Classic toolkit, for Touch screen devices scrollbar just disappearing. From my research it came out that I need to upgrade to 5.1.2 to resolve. which we'll do in future planning. I am currently looking for any workarounds for our clients ! Any suggestions would be helpful. Thanks in advance.

Please select the 5.1.1 version with the classic toolkit in the Touchscreen machine. Scrollbar isn't disappearing for dropdown.
