Has anyone encountered such a problem? In which direction to dig?

Answer 1

I found the reason on Stackoverflow - a bug with the action mode style in some Samsung firmware. The solution from the link did not work, but I managed to defeat the bug as follows:
Created a basic style

<style name="Widget.ActionMode">
<item name="android:background">?android:attr/actionModeBackground</item>
<item name="android:backgroundSplit">?android:attr/actionModeSplitBackground</item>
<item name="android:height">?android:attr/actionBarSize</item>
<item name="android:titleTextStyle">@android:style/TextAppearance.Widget.ActionMode.Title</item>
<item name="android:subtitleTextStyle">@android:style/TextAppearance.Widget.ActionMode.Subtitle</item>
</style>

And inherited its ActionMode style from it.
