    Default BufferedRenderer throws error when a renderer function causes another grid to update

    https://fiddle.sencha.com/#view/editor&fiddle/1o21

    Ext version tested:


    • Ext 5.1.3



    Browser versions tested against:


    • Google Chrome 55, FF 50, IE 11




    Description:
    When a grid with buffered renderer has a renderer function which causes a view update or something similar in another grid with buffered renderer an exception is thrown and the grid looks basically destroyed on the UI.

    Sencha Fiddle with reproduction scenario: https://fiddle.sencha.com/#view/editor&fiddle/1o21
    Basically it is the buffered grid from the example page with a second grid and a renderer function that calls ensureVisible.

    The error:
    Code:
    Uncaught Error: rendered block refreshed at 1 rows while BufferedRenderer view size is 52    at new Ext.Error (ext-all-debug.js:2225)
        at Function.raise (ext-all-debug.js:2263)
