[React Spinner] TSUI does not remove Spinner overlay so can't interact with page

[n-srg]

I periodically facing weird spinner behavior on my React app:

I run spinner by setting data-ts.blocking. After I remove this attribute (or set it to empty string '' does not matter), grey overlay and spinner animation disappear, but i can't interact with the page.
The reason is that
<div data-ts-spirit="ts.ui.CoverSpirit" class="ts-cover ts-spinnercover ts-transition" id="ts-spinnercover"></div>
blocks whole viewport. As shown above, it missing some classNames: _gui-hidden _gui-invisible

v9.3.8 and older

I can't make 100% repeatable case, but I face it every few page reloads. will update issue in case I will be able to make 100% working example

I came across similar problem. Also in a React app, when call show-spinner and then call dismiss-spinner in very short delay, a div.ts-spinnercover will cover the whole page making it irresponsible.
