During editing, merge inline style with overriding other author styles

testcase

On editable contents, If you backspace before a first character of a line, the line is merged to the upper line with merging parents' style to the inline style.
If there are conflicting styles in parent's styles, not the inline style of the parent but the embedded style of the parent is applied (as the attached test case).

This patch needs a test case demonstrating it fixes a bug; at minimum it shouldn't regress tests.

Why?

I added patch with newly added test case.
On the attached test case,
if you backspace on the start of the 2nd line,
the style for class (color:red) is merged,
but the  inline style (color:blue) is not merged because it's DoNotOverrideValues mode.
Then, as a result, only the style that was not applied is merged, and the color is changed!
I think merging inline style first can be a solution for that.
