Greetings from Syncfusion support.
We validated the reported issue with shared code block and able to reproduce the issue. When you place Grid within Tab component, the parent element’s height is not set to ‘100%’. So, the issue occurs in Tabs. Please set ‘100%’ to tab template and its parent elements like below code.
We will consider this as bug “ Rendering tab content with its default height” in our end. We will fix and include in our upcoming patch release which is scheduled on end of September 2019. You could keep track of the issue from the following feedback link.
