[GitHub] [incubator-superset] zuzana-vej opened a new issue #11331: Shifting cursor (forward) when editing Markdown with emoji

[GitBox]

zuzana-vej opened a new issue #11331:
URL: https://github.com/apache/incubator-superset/issues/11331


   When editing a markdown component with a specific emoji (which occupies two 
characters) - for example the start emoji which is by default on the markdown 
component, clicking on text places the cursor one character to the right and 
making editing confusing.
   
   ### Expected results
   
   Cursor stays at correct position
   
   ### Actual results
   
   Cursor jumps 1 step forward
   
   #### Screenshots
   It's hard without video, but here are few screenshots (I can share video if 
needed). In this example I am trying to correct "payouss" to "payouts"

   #### How to reproduce the bug
   
   1. Go to Dashboard, Add Markdown with emoji (e.g. the start shape)
   2. Try to edit a sentences (after the emoji) and see the cursor jumps around 
(deletes character forward, not correct one)
