Explanation

• What is the expected behavior?

• What is happening instead?
• spell checking for texts is disabled
  
• I believe issue was introduced in this commit a94f033
  
  It is not possible to enable spell checking because there is no way to change input template.
  

I think issue can be resolved by adding something like 'spellcheck' parameter in settings or provide ability to change input template

• What error message are you getting?
  no spell check
