Suddenly the tab slider is not showing, and it seems to be that the width css-property of the style attribute has an invalid charter (comma ,) in it. I have tried to reconstruct the behavior in TryMudBlazor but I cannot. I have no custom javascripts or packages in the page. I took a look at the code in MudBlazor repository, but I can't see anything that set the width to anything that should lead to a decimal number that is not culture invariant (.).

A copy of the element from the Chrome debug window is shown below:

<div class="mud-tab-slider mud-tab-slider-horizontal" style="width:46,861531896735656%;left:0%;transition:left .3s cubic-bezier(.64,.09,.08,1);;"></div>

Any ideas what can cause this behavior?
