Views strips HTML from content when grouping fields in columns in Table Format

I'm not sure whether something has changed, but I can't reproduce the HTML stripping here. If I have a field with HTML, it displays the same way whether it its own column or grouped.

Fields displayed in the same column:

<td headers="view-title-table-column--n_pwIg-AmyE" class="views-field views-field-title views-field-body">
<a href="/node/470" hreflang="en" data-once="views-ajax">Test with comments</a>
<p>Body text here with <strong>some HTML</strong>.</p>
<a href="/node/470/edit?destination=/admin/structure/views/view/duplicate_of_manage_corporate_active_requests/preview/page_1%3F_wrapper_format%3Ddrupal_ajax" hreflang="en" data-once="views-ajax">edit</a>
</td>

Fields displayed in separate columns:

<td headers="view-title-table-column--N3fpHc6FMWU" class="views-field views-field-title">
<a href="/node/470" hreflang="en" data-once="views-ajax">Test with comments</a>
 </td>
<td headers="view-body-table-column--Dxql8bimhMU" class="views-field views-field-body">
<p>Body text here with <strong>some HTML</strong>.</p>
</td>
<td headers="view-edit-node-table-column--8z0MW96QIvM" class="views-field views-field-edit-node">
<a href="/node/469/edit?destination=/admin/structure/views/view/duplicate_of_manage_corporate_active_requests/preview/page_1%3F_wrapper_format%3Ddrupal_ajax" hreflang="en" data-once="views-ajax">edit</a>
</td>

If the OP or anyone else has info on how to reproduce, please update the issue summary with specific steps. If that is not provided, this issue may be closed after 3 months.

Nine months has lapsed.

No update since then.

Closing.

Set following fields:
- "Content: Image"
- "Content: Authored by" [hidden] and in "Style settings" Customize field HTML "EM"
- "Content: Authored on" with "Rewrite results" {{ uid }} - {{ created }} Already here "Authored on" lost its EM while "Strip HTML tags" is "off"
- "Content: Title" and in "Style settings" Customize field HTML "H3"
All fields have "Add default classes" in "Style settings"

Format as table with:
Content: Image in column Content: Image
Content: Authored on in column Content: Title
Content: Title in column Content: Title

Results to a <td> where: "Authored by" loses its "EM" tag and the rewritten "Authored on" is wrapped in the Title's H3!
<h3>Author's name - Date <a href="article link">Title</h3>
Even if we wrap "Authored on" in a div it remains inside the title's H3
- Content: Authored on with "Rewrite results" <div><em>{{ uid }}</em> - {{ created }}</div>
Result: <h3><div><em>{{ uid }}</em> - {{ created }}</div> <a href="article link">Title</h3>

The only way to overcome is to manually group and format everything in title's "Rewrite results"
<div><em>{{ uid }}</em> - {{ created }}</div><h3>Title<h3>

So I see two problems: one with rewriting, where customized html tag is lost, and the second with table format where grouping fields in a column strips previous html and wraps fields in the last field's tagging.
Anyway one would expect that each field preserves its own html tagging ans style settings unless it is specified to "Strip HTML tags".
