What is the current behavior? Describe the bug
If i have a number list in a word document, which has a soft line break at the end of the first row and after the first word of the next line exists a full stop, this first word will not be appear in TinyMCE when i copy the content from the word document and insert it into the TinyMCE editor.

Please provide the steps to reproduce and if possible a minimal demo of the problem via fiddle.tinymce.com or similar.
Make a number list with a soft line break at the end of the first row and set a full stop after the first word after the line break. (see screenshot1 point 2)
Then copy the content from word to TinyMCE and the first word with the full stop after the soft line break will be disappear. (see screenshot2 point 2)
For comparison in both screenshots is a soft line break without a full stop after the first word shown, which will be correct inserted by TinyMCE. (point 1 on both screenshots)

What is the expected behavior?
That the TinyMCE doesn't drop words of the content when it will be copied and inserted from a word document. Regardless if there is a full stop after the first word after the soft line break or not.

Version: TinyMCE 5.1.6
Browser: Safari on MacOS, Chrome & Firefox (MacOS & Windows)

This issue doesn't exist in TinyMCE with premium word plugin.
