I have a very simple .Net MAUI project with three (XAML) pages. The project compiles and runs without any errors or warnings.
When I edit one of the XAML pages and type a < character, the following intellisense pop-up is displayed:

NOTE: The pop-up is missing several XAML statements that should be present.

When I edit a different XAML page, the following intellisense pop-up is displayed:

This time, the pop-up contains ALL of the XAML statements that one would expect.
In two of the three XAML pages, the pop-up works correctly (all statements displayed), but on one page, XAML statements are always missing -- I cannot figure out why.
Initially, I thought it may have been contextual in nature, that is, showing only those XAML statements that would be valid at the insertion point. However, in each file, my insertion point was directly below a ScrollView statement.
Any ideas why intellisense works with some XAML pages and not others? Is this a known bug in Visual Studio?
Thanks in advance.

Update: 19-Sep-2022

I think I have confirmed why this is happening -- on XAML pages WITHOUT any comments between the following lines:

<?xml version="1.0" encoding="utf-8" ?>
<ContentPage ...

... intellisense works just fine. For example, when I hover my cursor over the ContentPage node, the following is displayed:

... and when I try to insert other nodes, intellisense is present (all options are present in the pop-up).
However, on a page that intellisenses does NOT work, I have a large comment block between the two lines above, for example:

<?xml version="1.0" encoding="utf-8" ?>
<!--
  Large comment block (approximately 90 lines.
-->
<ContentPage ...

When this comment block is present, intellisense stops working, that is, if I hover my cursor over the ContentPage node, nothing is displayed and when I try to insert other nodes, the following popup (which is missing all options) is displayed:

The only way around this (so far) is to remove the comment block, or move the comment block to the bottom of the page, after the closing ContentPage node.
