Description

Originally by mju


This is related to https://github.com/vaadin/framework/issues/3584

The ticket was resolved to fix the resizing of a table in a formlayout. The tables are now resized properly, and in Internet Explorer, Edge and Chrome it works slowly.
But in Firefox, the size of the table very often freezes a short time when the formlayout is being resized. It takes a bit (<1 second, but very noticable) for the table size to update.
This should not happen, instead the size should update smoothly like in the other browsers.

Research direction

Start with the FormLayout table-resizing implementation and the related issue #3584. Reproduce resizing in Firefox and compare it with Internet Explorer, Edge, and Chrome to identify the visible freeze. Done means the table size updates smoothly during FormLayout resizing in Firefox without regressing the other browsers.
