Hello @sayaliwakch ,

check how you are making the html fields read after state closed,

If you are using a UI Policy or Client Script, ServiceNow loads the full HTML editor in the background and then disables it, which causes the height calculation bug on tab switch.

I would recommend create a Record-level Write ACL (or Field-level Write ACL) that evaluates to false when the State is Closed.

When an ACL prevents write access on form load, ServiceNow completely skips rendering the TinyMCE editor iframe. It just renders the HTML content inside a standard, flat <div>. This flat div will dynamically resize perfectly, eliminating the tab-switching bug entirely.

If my response helped mark as helpful and accept the solution.

Hi @sayaliwakch 

It seems , with other field , your html field is also Read Only.

Please check your existing UI policy ,client script or data policy

I believe it's default OOTB behavior when HTML field is readonly via UI policy it takes up complete space and doesn't auto minimizes it

check this KB and apply this fix of removing attribute from dictionary

The HTML field is showing a blank space and not reduced to lesser size when the field is made read-o...
