RichTextBlock Fail to autowrap when use image

[cuwings]

I’m using ue 4.26 engine and find RichTextBlock cannot auto wrap when use image decorator.

I tried like this topic:

Richtextblock fail to auto wrap

(1) create a new richtextblock, set wrap width and wraping policy(Allow per character)，add a text style set with a image dectorator; (2) set text with <img id="Default1"/><img id="Default1"/><img id="Default1"/><img id="Default1"/>... (3) the result is the richtextblock fail to auto breakline； I try to debug, and find the fellowed issue. In Engine\Source\Runtime\Slate\Private\Framework\Text\TextLayout.cpp:614, the CurrentRunIndex may be repleased by BreakRunIndex. for (int32 BreakRunIndex = …

but richtextblock still don’t work.

Is there any way to fix this problem?
