BUG – Heading and Text Editor issue

It seems I’m having a bug with Elementor latest version updated yesterday – 3.16.3 – but I’m almost sure it was already happening in version 3.16.1 when I started a new site some days ago.

Both the heading and text editor elements do not break lines, and depending on the screen size or even the section size within the container (which is already set to flex), when the line reaches the end of the section, it starts rewriting at the beginning of the line, and all the text ends up on a single line.

I just did a fresh installation of WordPress on another subdomain, and it seems the error occurs after installing ElementsKit plugin and creating a header or footer, or even after changing some simple global settings like colors and fonts – which shouldn’t interfere much with this. These were the only two modifications I’ve made before the issue begins. I’ve already reverted to the original font settings and disabled EK, and I only have Elementor enabled, but the problem persists.

Has anyone else seen this behavior or experienced something similar?
