When the tabstrip have multiple tab within a limited width, the tabs are rendering outside the limit of the tab.
The component behavior should (perhaps by options configuration):
This can be reproduced using the StackBlitz of the tabstrip.
Like the SAPUI5 object page control, it is a tabstrip with horizontal orientation of the tab headers but vertical allignment of all tab sections within the tab content container. If the user clicks on one tab header, the tab content container will be scrolled down to the tab section linked to the tab header.
A preview is given in the link below.
It seems to be impossibly hard to make it so that when a TabStrip is in a container that the content area is able to fill the remaining space rather than fitting to the content. I have seen that there are work arounds for what appears to be the same issue for the jQuery KendoUI library but it looks like a hack rather than a true solution. (One shouldn't have to go to the code behind to make this happen). A simple "fillRemainingSpace" (or similar) would be perfect and have the TabStrip handle the rest. I expect this is pretty common scenario for anyone making application like UI websites.
