rForbiddenTags Prevents ColumnListItem to Switch Its Busy State

[boghyon]

URL (minimal example if possible):

https://openui5.hana.ondemand.com/#/sample/sap.m.sample.Table/preview

Steps to reproduce the problem:

1. Open the above example page
2. Set the busy state of one of the ColumnListItems to true

What is the expected result?

The item becomes busy and displays a BusyIndicator in it.

What happens instead?

Since ColumnListItem is rendered with the HTML tag <tr>, which is one of the forbidden tags, enabling busy state is skipped.

openui5/src/sap.ui.core/src/sap/ui/core/BlockLayerUtils.js

Line 17 in 7d36306

rForbiddenTags = /^(?:area|base|br|col|embed|hr|img|input|keygen|link|menuitem|meta|param|source|track|wbr|tr)$/i;

Any other information? (attach screenshot if possible)

@boghyon this is a known limitation as you already see the console message. we do not support busy for the ColumnListItem

I would like to know the reasoning, why it is not possible to set the busy indicator for this control. From my point of view it makes sense to mark a list item as busy.

Also, even though there is a console message to indicate that the BusyIndicator is not supported, the official documentation does not mention this limitation.
