We've observed an issue related to documents with customized header styling. Specifically, when such documents are converted to HTML, the headers receive an explicit font-weight: normal style.
Subsequently, when this HTML is passed through htmldiff-js to generate differences, new elements are introduced for insertions and deletions. These tags do not carry explicit font-related styles. As a result, they inherit the styling of the surrounding elements—in this case, the h3 tag—leading to inconsistent font appearances in the diff output.
For example -
<div #newHtml><div><h3 style="margin-top:12pt; margin-left:39.6pt; margin-bottom:12pt; text-indent:-21.6pt; text-align:justify; line-height:108%; font-size:11pt; -aw-import:list-item; -aw-list-level-number:1; -aw-list-number-format:'%1.'; -aw-list-number-styles:'upperLetter'; -aw-list-number-values:'8'; -aw-list-padding-sml:10.6pt"><span style="-aw-import:ignore"><span style="font-family:Arial; font-weight:normal">H.</span><span style="width:10.6pt; font:7pt 'Times New Roman'; display:inline-block; -aw-import:spaces"> </span></span><span style="font-family:Arial; font-weight:normal; text-decoration:underline">Return of Information</span><span style="font-family:Arial; font-weight:normal">Contrary to popular belief, Lorem Ipsum is not simply random text.
