When I'm in a Chart object, with the Styles Sidebar deck, with the Page Styles category selected, and I press "New Style from Selection", I get a dialog for entering the new PS name; but after entering it and Ok'ing - Nothing happens. Similarly, if I try to delete a custom Page Style created in Calc, outside the Chart - by using the Delete command on the context menu - this _seems_ to work, in that the list loses the item; but if I switch style categories to another category and back - the style reappears. Same if I exit the chart object.
Which component is that? In my testing, both in Writer and in Calc, entering a chart (or creating it), the irrelevant sidebar panels are properly hidden.

(In reply to Mike Kaganski from comment #1) > Which component is that? Oh, sorry, forgot to mention that. I created the chart inside Calc. The version info is: Version: 24.8.1.2 (X86_64) / LibreOffice Community Build ID: 87fa9aec1a63e70835390b81c40bb8993f1d4ff6 CPU threads: 4; OS: Linux 6.6; UI render: default; VCL: gtk3 Locale: en-IL (en_IL); UI: en-US Calc: threaded
So - likely GTK-specific (or otherwise specific to platform/integration - just GTK inherently works differently compared to other integrations).
