spellCheck didn't work in iOS 13.5 +

[MohitAgrawal96]

I want editor like user don't acess auto correction and auto completion feature for the editor. I simply modified in rich_editor.html file with

this html code . so user wouldn't able to pick from suggestion in keyboard. but my issue is this code perfectly run in lower iOS versions like 13.2.2 . but in iOS 13.5.1 all thing works fine expect spellCheck property for this div class. in this version of OS spellCheck does not work . so user got confused that where the misspelled words are located . if spellCheck works fine then user can easily trace where my misspelled words are located.
Please help me out, I search a lot for this issue but I failed to achieve my goal .
Thanks and Regards,
Mohit Agrawal.
