Powerpoint to HTML conversion issues

I am converting powerpoint presentation to HTML using Aspose.slides. While checking this i found few issues with conversion
1) If I have numered bullets, conversion is not proper (see slide no 1)
2) If I have some text which is ITALIC, rendering is not proper espacially open converted html in IE or firefox (see Slide no 2)
3) If I have Superscript text in the slide, in html it is appering as compressed, check this on chrome. (see Slide no 3)
4) If I have a table, its border colour changes (see slide 4)
5) If I have Arial Narrow font used, text is getting overlapped (see slide 5 footer)
6) If I have arrow image in between text, it is getting overlapped (see slide 6)
7) Arial Narrow text not rendered properly (see slide 7)

I have attached both powerpoint presentation as well as converted HTML files for your reference.

For SLIDESNET-38602 - Superscript issue - This issue is seen only on chrome and edge browsers. We have observed that this issue is happening due to textlength being smaller for the tspan for that superscript text. If we increase textlength, issue gets resolved.


This is the HTML for superscript text
st

If I change textLength to <span style=“background-color: rgb(255, 255, 255); color: rgb(34, 34, 34); font-family: Consolas, “Lucida Console”, “Courier New”, monospace; font-size: 12px; white-space: pre-wrap;”>20.374335 it resolves the issue.

Can you please add this to your next build?
