tracker issue : CF-4205050

Problem Description:
Create a cfm page with cfform and have a CFGRID on the page as well.
When you submit the error occurs.

Steps to Reproduce:

1.Create a cfm page with cfform and have a CFGRID on the page as well.
[gtest.cfm]
<cfscript>
  qEmp = queryNew("id,name", "Varchar,Varchar",
                       [["a", "name1"], ["b", "name2"], ["c", "name3"]]);
</cfscript>
<cfform>
<cfgrid format="html" name="grid1" query="qEmp">
  <cfgridcolumn name="id">
  <cfgridcolumn name="name">
</cfgrid>
<cfinput type="submit" name="submit" value="submit">
</cfform>

2. Click submit on the cfm.

Actual Result:

Nothing is being displayed on the screen. Checking coldfusion-error.log, the error message is appended:
"The submitted cfgrid form field is corrupt (name: __CFGRID__CFFORM_1__GRID1 value: [, ])"

Servlet.service() for servlet [CfmServlet] in context with path []
threw exception [ROOT CAUSE:
coldfusion.filter.GridFieldProcessor$CorruptGridFieldException: The
submitted cfgrid form field is corrupt (name:

at coldfusion.runtime.CfJspPage.invoke(CfJspPage.java:262)

This is reproducible on ColdFusion 2018 Update4 and 2016 Update 11.
It is not reproducible on ColdFusion 11 Update 19.

Any Workarounds:
This behavior is simlar to the bug below which have logged past:
https://tracker.adobe.com/#/view/CF-3842284

However, in CF-3842284, the error is generated when enctype=multipart/form-data is specified to cfform.  This case is exactly reversed behavior. The error can be avoided when enctype=multipart/form-data is specfied to cfform.
