The stack shows 1070 repeated frames of:
- StructElementObject.ProcessChildPrimitive(...)
- StructElementObject.CopyPropertiesTo(...)
The StructureTree import is traversing a cyclic StructElement graph (or equivalent re-entrant child chain) without a recursion guard.
During this recursion, indirect object resolution repeatedly re-enters the same compressed object:
- reference.ObjectNumber = 554
- context.CurrentIndirectReference.ObjectNumber = 554
- TryGetIndirectObject(554, ...) == false at re-entry

It would be nice to have the ability to search text in documents. Use case: I needed to replace some keywords with images. I can insert image at the current position, but there is no way to insert it after some text.

When imported in the WordsProcessing model, the current HTML doesn't respect the defined column width and all columns have identical width:
<colgroup>
<col span="1" style="width: 33.3302%;">
<col span="1" style="width: 17.5658%;">
<col span="1" style="width: 49.104%;">
</colgroup>Observed result:
Expected result:
Workaround: use the width property as follows:
<colgroup>
<col span="1" width="33.3302%">
<col span="1" width="17.5658%">
<col span="1" width="49.104%">

Multiple CSS classes on an element are not correctly resolved when converted to inline styles.
Before:
.TelerikNormal {font-family: Calibri;font-size: 14.6666666666667px;margin-top: 0px;margin-bottom: 0px;line-height: 100%;color: #000000;}.TelerikHeading3 {font-family: Calibri Light;font-size: 22.6666666666667px;}<p class="TelerikNormal TelerikHeading3"><span>Test</span></p>Due to order priority, the TelerikHeading3 values override the TelerikNormal values. The font-size becomes 22.6666666666667px.
Convert:
provider.ExportSettings.StylesExportMode = StylesExportMode.Inline;
<p style="font-family: Calibri;font-size: 14.6666666666667px;margin-top: 0px;margin-bottom: 0px;line-height: 100%;color: #000000;"><span>Test</span></p>
