f.rich_text_area stopped working with a yarn update

• Ruby ruby 2.6.6-p146
• Rails 6.0.0
• gem 'simple_form'
• gem "bootstrap_form", "~> 4.0"

• gem 'webpacker', '~> 4.0'

  <%= simple_form_for @doc do |f| %> … <%= f.label :content, "blah-blah":" %> <%= f.rich_text_area :content, rows: 6 %>

Had been working fine, but stopped working after yarn upgrade (needed a bootstrap upgrade). Now just get a small rounded corner box which can't be entered into. My reading is that ActionText went from v6.0.2 to v6.0.3 with the upgrade and this is on same line as the label instead of a new line hence the colon.

If change to just text_area a text box shows up as expected.

Stackoverflow didn't seem to have any similar reports. I have several similar forms and they all use simple_form so can't easily check if form_for would have the same problem. (A while back I tried to create the pages without simple_form but I couldn't figure out how to get the features of simple_form that I neede. In other word, love the gem.)

Looking at log I ran brew upgrade yarn and yarn upgrade again, but still no ActionText.

I ran a simple test without simple_form and the problem continues, so not a simple_form problem. Sorry for the noise.
