I created a simple visualforce which has a form and an input field. I have give a help text to pageblocksection. Below is my VF page code.
<apex:page showheader="true" sidebar="true" name="AMP" >
<apex:includeLightning />
<html xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink">
<apex:form >
<apex:pageBlock >
<apex:pageBlockSection >
<apex:pageBlockSectionItem helpText="Enter valid install url format">
<apex:outputLabel for="txtUserName" value="User name123" />
<apex:panelGroup >
<div class="requiredInput"><div class="requiredBlock"></div>
<apex:inputtext html-placeholder="<USER NAME>" id="txtUserName" ></apex:inputtext>
</div>
</apex:panelGroup>
</apex:pageBlockSectionItem>
</apex:pageBlockSection>
</apex:pageBlock>
</apex:form>
</html>
This help text is broken in some salesforce account but not is all...
I have one Group Edition account in which the helptext is broken. Below is the image
And Now I have one snap shot a developer edition with same visual force code.
