BUG on Rich Text feature! - Always highlight a letter

I found this nasty bug on the Rich Text option inside database table. Basically, I can’t place the locator (that blinking vertical line that indicates where you type something) without having it to highlight a letter. This is problematic because the highlight will replaces anything its highlighting with whatever you input next.

For example (see pic below), if I place the locator around the M letter, it will highlight the M instead, and if I type something like letter H, the letter M will be replaced with H and the highlight will move to the next letter. Basically if I continue writing, the rest of the text after the highlighted letter will be replaced one by one letter, so I can only write properly if the locator was placed on the very end of paragraph.

This behavior persist when editing database directly from the Edit Site option, as well as the Database Collection menu. Tested on Vivaldi & Opera browser.

Can anyone else confirm this problem? Looking for solution from the devs.
Thanks.
