Backspace in beginning of a *styled* line does not affect the line positioning

Jodit Version: 3.4.29

Browser: Chrome
OS: Windows
Is React App: True

Code

// Example 1
<div>This is</div>
<div>my line</div>

// Example 2
<div><span style="color: rgb(0, 0, 255);">This is</span></div>
<div><span style="color: rgb(0, 0, 255);">my line</span></div>

Expected behavior:
On both examples, when standing on the beginning of the second line (where the text 'my line' starts), I would expect that the second line's text will jump up to be at the end of the first line (like so - 'This ismy line')

Actual behavior:
In example 1 it works as expected, but in example 2 I keep typing the backspace key without any response.
