Editable fields with HTML are getting reformatted and increasing font size

[midspace]

In Reports.NET for the WEB MVC,
We have a number of reports that use Editable fields with HTML.
I have attached a sample template we use for testing.

We are upgrading from an older 2018 version of Stimulsoft, and see issues with the Editable fields when editing the fields. The font size and line spacing are changing after opening editable fields, per the attached screenshot.


Steps to reproduce:
1. Open the Stimulsoft demo site: https://designer.stimulsoft.com/
2. Open the following attached sample report. AHK0000KK.mrt
3. From the top, click the "Preview" tab.
4. The View should change and show a rendered report.
5. From the bottom right, change the Zoom level to 150%
6. From the toolbar, click the "Editor" button (next to the magnifying glass),
7. The editable fields should be highlighted in a pale yellow.
8. Click in the first editable field, and the backing HTML should appear.
9. Click out of the field, anywhere on the report. The editable field should change back to text.
10. From the toolbar, click the "Editor" button again. This should turn off the editable fields.
11. The editable field we had clicked in, will change. All the text in it will get bigger. And the line spacing will increase. We expect to see no change to font size, line spacing or indentations with the bullet points.

I have attempted to determine which version this issue was introduced, and it looks like there have been several bugs introduced and fixed over several versions.
Version 2025.4.1 appears to be when then font size issue was introduced. It was not there on previous version.
The line spacing issue has been there for longer.
Older versions removed the indent on the UL/LI bullet points, but it was fixed in 2025.4.1.
None of these issues were present in 2018, except for the line spacing issue, which would only happen after editing the field, and then changing the zoom.
