In Code View Bolded Text Has Strong tag wrapped around each character

[codingsince007]

When copying a word document over to create a new page, the formatting carries over...mostly. But when you look at the content in code view there are extra tags that is added which make the code look sloppy.

Here is a sample of the extraneous code added when viewing the code;

<p><strong>S</strong><strong>H</strong><strong>A</strong><strong>RING INFORMATION WITH ADVERTISERS </strong><strong>OR </strong><strong>OTHER THIRD </strong><strong>P</strong><strong>A</strong><strong>R</strong><strong>T</strong><strong>I</strong><strong>E</strong><strong>S</strong></p>

Why is it adding a strong tag around each character?

I am adding a screengrab of the Dev Tools and of WordPress 5.0 UI.

Did you try pasting the exact same thing into the Classic Editor, to isolate the culprit?

I have not. I know that Word sometimes causes issues but because most of the other text was fine it seems to be related to text that has bold formatting.
