205537 - multiple generic fonts (monospace / non-monospace) cause wrong size

Status: RESOLVED DUPLICATE of bug 175415

(Core :: CSS Parsing and Computation, defect)

Description

[Yuying Long]

Build: 05-13 trunk build on All platforms

Steps to reproduce:
1. Go to page: http://www.w3.org/Style/CSS/Test/CSS1/current/sec522.htm
2. Please compare the fonts display in ".five {font-family: monospace;}" and
".seven {font-family: monospace,serif;}" section are differently.
- I expected them are displayed same; IE and Sarafi have the same display with
these two.

Attachment: testcase

Confirming problem (NS7/Pheoenix/current mozilla build), the two lines display
differently because the font-size applied isn't the same. The <p> which has
rule .seven {font-family: monospace,serif;} is displayed on screen in a
monospace font but with the font-size set in prefs/appearance/fonts for
proportional fonts.

To see the bug you have to set different font-size for monospace and
proportional fonts in preferences (default configuration I think).

I think the basic problem here is that we have bugs when we have multiple
generic fonts at the end of the font list.  I thought we had other bugs filed on
that, but I can't find any.

Yep, it is a dup of bug 79074 (although its summary isn't suggestive of that).

Undupping on further thougths, it might be easier/clearer to leave this bug on
its own.

The issue is the parsing of multiple "generic1, generic2" which has been
mentioned on several occasions but hasn't got a distinct thread so far.

a distinct thread so far ...apart from bug 78517.

Comment 6

[Mathieu Parent]

Is it dup of (or at least linked to) bug 175415 ?

Comment 7

[Gérard Talbot]

Yes, Mathieu: you are perfectly correct. This bug is a DUPLICATE of bug 175415. This bug is not a duplicate of bug 79074.

The nice thing about this bug 205537 is that there is a good testcase webpage coming from the current CSS1 test suite which could serve as a testcase here.

I believe we should resolved bug 205537 as duplicate and then resummarise bug 175415; one reason why is that discussion over at bug 175415 has been well developped for some time.
