RadEditor maximize and minimize issue in Edge Browser

[Sachita]

Current Version - 2021.3.915.45 and .NET 4.8

Tried with ContentAreaMode="DIV",but still no luck.

In Edge and chrome ,RadEditor is not maximizing or fit to page.

But ,IE it works fine.

    EnableEmbeddedSkins="true"
    EnableAjaxSkinRendering="true"
    Height="390px"                                             - tried increase and decrease
    Width="99%"                                                  - - tried increase and decrease
	EditModes="Design,Html"
    AutoResizeHeight="false"                               - Tried with true
