Spreadsheet bad performance on setting font size to multiple cells

The performance in the latest official version is significantly worse compared to older versions (2017.1.117 and 2018.1.118 tested).

Reproduction of the problem

Dojo example.

  1. Click a cell
  2. Press Ctrl + A
  3. Select a font size from the dropdown in the Spreadsheet's toolbar

Current behavior

The UI freezes and remains unresponsive for minutes.

Expected/desired behavior

The new font size is applied without significant delay.
