Why is uistyle("Icon",'error') making a transparent icon when the UITable is not on the first tab of a tabgroup?

Breif description of what I am working on:

I am attempting to build a custom component in MATLAB appdesigner (R2023b) that functions as status bar/message center that I can use in any applications I build going forward. The plan was the have a tab group with three tabs: the first would have all messages (including 'warnings' and 'errors'), the second would contain only those designated as 'warnings', and the third would contain only those designated as 'errors.' I wanted each tab to contain a table where each row is a single message with a message ID. I would then use the 'Icon' feature in the 'uistyle' function to display 'warning' and 'error' icons in the appropriate message cells.

The issue:

The 'error' icon on any UITable not on the first tab of a tab group always appears to be transparent. I've built up the simplest possible custom component that recreates the issue and included the code at the bottom of this post. In it, you can see that I use a for-loop to set the exact same uistyle on each table. The only difference is the tab that table exists on. For any tab that isn't the first one, the error icon color gets messed up. This doesn't appear to happen for any other icon types. Screenshots of my example code exhibitng the behavior are included below. This seems pretty clearly like unintended behavior, but I'm hoping for a way to work around it anyways.

A friend of mine has since tested this is 2022b and found that the issue does not exist in that release. Here's a screenshot of his:

That is interesting.

Here is a workaround for now, you can just hardcode the path to the file as such:

addStyle(Tablelist(ii),uistyle("Icon",'C:\Program Files\MATLAB\R2024a\ui\icons\24x24\error.svg'),"cell",[4,2]);

above is the path for mine. Yours will be in the R2023b folder.

Thank you! I was wondering if creating my own png would be a viable workaround, but linking directly to the original file is much preferred! I can't imagine that the icon I would have produced would look very good by comparison...
