Easily reproducible on http://tests.ckeditor.dev:1030/tests/plugins/tableselection/manual/nestedtable.

The selection always starts in the last row of nested table and it can end:

1. right after text in the last table cell,
2. in the last table cell (containing whole cell).

In the 1. case the text after nested table is not cut when it should be (rest of the content is cut properly).

Case 2. works good, whole selected row and text after nested table is cut. The content of Cell 2.2.2 should be also cut which is covered in #787 fix. (well, that's not the case here as this in not tableselection plugin dependent bug, I assume it is some Safari issue only, as the gif was captured in Safari, because it does not happens in other browsers).

Checked also if it is not a native issue https://codepen.io/f1ames/pen/Bwabjd, but does not look like one as the selection behaves a little different there.
