If you have a feature suggestion, please add it on the Feature List instead.

Expected behavior.

Using Froala Editor with the htmlUntouched setting, you can type bold text, unbold, and then add a space. The space is added. The current styling is preserved.

Actual behavior.

Chrome + Froala 4.2.2
Safari + Froala 4.1.4 Chrome + Froala 4.1.4
The space is added as a regular space and collapsed by the browser. It appears as if the space is deleted.

In Safari + Froala 4.2.2, the space is added and bold is re-enabled.

Steps to reproduce the problem.

In Froala Editor, with the setting htmlUntouched set to true, type a bolded word. Unbold and then type a space.
