So request is to change splitbar aria-label so that '50' (or whatever percent) is removed from aria-label. I have tried changing it through splitterBarAttributes. With this setup, NVDA still reads 50 Test separator.
<kendo-splitter
orientation="vertical"
max="1000">
<kendo-splitter-pane
max="500"
[splitterBarAttributes]="{ 'aria-label': 'Test' }"
>
<app-my-component></app-my-component>
</kendo-splitter-pane>
<kendo-splitter-pane
min="500"
[splitterBarAttributes]="{ 'aria-label': 'Test' }"
>
<app-my-component></app-my-component>
</kendo-splitter-pane>
</kendo-splitter>
