Summary: Changelog: [Internal] # Fabric 1. If `start` and `end` parameters in `setTextAndSelection` are -1, we don't move the cursor. Previously the cursor would be moved to beginning of text input. 2. In view commands, do not validate `eventCount`. It is passed in as undefined from JS because Fabric's text input doesn't use `eventCount`. # Paper 1. If `start` and `end` parameters in `setTextAndSelection` are -1, we don't move the cursor. Previously the cursor would be moved to beginning of text input. Reviewed By: shergin Differential Revision: D20538290 fbshipit-source-id: c7aeddc25f58697254474058ce901df958321f7c
