This one has been around forever, but I always figured it would be fixed at some point and never reported it.
Easily replicated:
Create a rich text widget, add some text.
On the canvas element, highlight some text and hit the B button to bold it - it creates a < b > tag on the text
Use the panel on the left, highlight some text and hit the B button to bold it - it creates a < strong > tag
I got the entire post completely wrong as I started it, got a phone call, then continued lol
The actual issue is the bold formatting button, not the shortcut. If you use the B button when highlighting text in the bricks canvas it inserts < b > if you do it in the editor on the left panel, it inserts < strong >
Hate to be a pain @Matej and @timmse, but just noticed a similar issue with the italic button - in the builder canvas it creates an < i > tag, and in the rich text editor on the left it’s < em >
Zero priority on this again, just noticed it and since this thread was here, decided to flag it
