If you include an IMG in a fixed-width, spanned (multi-column) table cell TD AND there are no rows that access the cells individually (unspanned), the width of the cell exceeds the fixed width by an amount proportional to the displayed width of the image even when the displayed width of the image is less than the width of the cell.

Depending on the content of the cells involved, the content of a neighboring cell to the right in a parent table may be (humanly) unreadable as a result of overlapping rendering.

Reproducible: Always

Steps to Reproduce:
1. See attachment for sample HTML
2. Optional: adjust browser window width to see interaction between adjacent content when problem cells are contained within a nested table.

Actual Results:  
Table cell TD width exceeds specification even when displayed IMG width is less than that of the cell width specification.

Expected Results:  
Fit the image within the specified space when the displayed IMG width is less than the specified cell width.

Attachment: Demonstrates cases of excessive cell width

When a problem cell is within a nested table, the width of the outer table/table cells is/are not adjusted with the width of the inner table. You can see this by playing with the width of your browser window and watching the right float overlap the left float before it hits the outer table border and is forced below the left float.

If there are neighboring cells in the outer table to the right of the nested table (not shown in this example), the excessively wide nested table content "spills over" into the right neighbor(s) of the outer table.

Mozilla1.7 does the same here, so not a (recent) regression.

this is wfm with a recent nightly (and probably 3.5)

Marking this as Resolved > Worksforme since the issue no longer is reproducible on the latest versions of Firefox Nightly 95.0a1 (2021-10-21), beta 94.0b9 or release 93.0 on Windows 10. Cross checked with Edge and Chrome and the tables are the same when changing widths.
If anyone can still reproduce the issue either re-open it or file a new one.
