@Ziad-Mid this looks much better, almost complete!
I would like to ask you to test it not only with TextArea, but also with TextFlow - you can use this reproducer https://github.com/andy-goryachev-oracle/Test/blob/main/src/goryachev/bugs/TextFlow_ExtraSpace_8330559.java

Notice how the layout is still not right in some places when the window is resized (the screenshots are from a combined branch of this PR + #1988 but the result is still the same, I think):

Also, could you try using the monkey tester and try TextArea/TextFlow (and possibly Text/TextField as well) with RTL as well as mixed text.  Please see if you can verify that the layout info is reported correctly, and the shapes are correct.
