Not all notebook annotations displayed when multiple added to same node before refresh

[dufaultc]

When adding annotations to a Jupyter Notebook file, I have found that if adding two annotations to the same paragraph, where the second is later in the paragraph than the first, if I do not refresh the page before adding the second one, it will not appear on the notebook view. It does appear under the annotations tab.

I believe this is because the second annotation does not get assigned the correct start and end node, and thus the below error occurs.

Where the annotation failing to be loaded has the below information

Looking at the html, it appears 28 is the length of the text before the first markus annotation added, thus the second annotation is trying to be added to the wrong node, causing the error.
